Re: [Mono-winforms-list] Drawing in a winform using Gtk C# in Xamarin Studio
I can confirm you're working on a GTK# project and not on a WinForms one. Mono can run WinForms apps (with some bugs), but doesn't have a WinForms designer. So if you wanna build a WinForms app with a GUI designer, you'd need to do it from Windows using Visual Studio or SharpDevelop. If you wanna build a desktop app from Xamarin Studio with a GUI designer, I think GTK# is your only choice. Note that there's another interesting GUI toolkit: XWT (https://github.com/mono/xwt), but it still doesn't have a designer either if I'm not mistaken. Anyway, I've never used GTK#, so can't help you with it. But I found this after a quick search, which might be useful: http://stackoverflow.com/questions/9113069/how-to-use-gdk-library-in-c-sharp-mono RoboPi wrote Thanks for the quick reply.

Re: [Mono-winforms-list] stuck with WinForms issue, not sure how to proceed
Hello, I know I'm a bit late, but just in case, I'll reply anyway. What I'd do is retrieve the Mono WinForms source code, then hack away to figure out what's wrong... Then you can just swap the Mono WinForms DLL with the one you built. Getting the WinForms project to build can be tricky, though (haven't tried lately). Sources: https://github.com/mono/mono/tree/master/mcs/class/System.Windows.Forms RhinoNY wrote Hi there, I have a Windows Forms custom control assembly which I have authored that does not run under Mono and I’m stuck trying to figure out why. I have provided a link to the testbed exe and the DLL below. Both target Framework 2.0. The DLL has a custom splitter, group bar, and navigation bar that I have authored. http://www.ryanrogers.com/monotest.zip I have ran both the DLL and EXE through Mono Analyzer and there were no issues found. Of course, I make no p/invoke calls or anything like that. I have compiled under VS 2010 as well as Mono. No warnings or errors compiling with either. I used the CSC.exe syntax out from VS and ran it through the Mono compiler. However, it doesn’t matter whether I run the MS-compiled assemblies of the Mono-compiled assemblies. In both cases I see a stack overflow warning (when run with –verbose), and the UI never launches. Everything runs fine using the MS runtime. I have tried both the “latest” and “stable” builds of Mono, and get the same result. I’m new too Mono, but a .Net veteran. How do I get more info out of Mono so that I can tell what is causing the problem? I know it’s my NavBar / GroupBar control that is causing the issue, as when I remove their creation from the testbed exe, it launches. So something these controls are doing is causing an issue, but I have no idea what, and am not sure the best way to diagnose this using Visual Studio. They are quite complex controls so I need some way to diagnose this. Do I need to be running MonoDevelop? Was hoping to avoid that... Are there some log files or logging options I'm overlooking?

Sadly, GDI+ and WinForms are simply buggy, especially on Mac.

Re: [Mono-winforms-list] Port winform .NET 4.0 app to Mac OSX
Any idea where to start? Trying to get your app to work with Mono on Windows was a good first step. I take it you can't make your app public, right? Or maybe try to make a reduced test case? If WebBrowser is not supported or converted is there any way round this? I'm not sure what the best solution would be. But you could do something like detect the OS, and if it's Mac, do something else (like using MonoMac to use native widgets? May not be easy to make it work with WinForms, though). Talking about that, for the info, what the Mono team suggests doing is having a different UI code depending on the OS, if you can afford it. Like, have some kind of interface, and if on Windows, use WinForms, and if on Mac, use MonoMac/Cocoa.

Re: [Mono-winforms-list] New install of C Sharp, using System.Winforms not found
In the monodevelop there was some kind of design page, although different from visual studio; It must have been the GTK# designer (an alternative to WinForms). Can you describe how I would build it in visual studio but then test it on linux?? Just build your application normally on Windows, and then you can simply test your app directly on Linux (either the binaries or the sources, both are compatible with the Mono runtime and MonoDevelop respectively, without any changes). So it's all pretty straightforward. Note that no matter what, you *will* need to install the Mono WinForms package to run WinForms apps, if you don't already have it. It's installed by default in OpenSUSE if memory serves.

Re: [Mono-winforms-list] New install of C Sharp, using System.Winforms not found
You didn't even need Mono or MonoDevelop for Windows, actually (although it can help to do preliminary tests before checking Linux out). What I meant is build your app with Visual Studio, then test it on Linux with Mono. So you use the WinForms designer of Visual Studio. MonoDevelop only has a GTK# designer. No WinForms designer, no ASP.NET designer, no Silverlight/Moonlight designer, and no WPF support at all. But on the bright side, since Mono is an open project, you can fix anything you deem not acceptable. iBradleyAllen wrote: ok cool, I downloaded the files for windows and got it setup in visual studio, then did debug in monodevelop and it worked; then made the file in md. no it didnt have any visual designer for the winforms stuff, i had to open a gtk# new solution and then it did. but i noticed adding items from the toolbox into the design area some did not have any properties? Its not acceptable to NOT have the visual designer mode.

Re: [Mono-winforms-list] WinForms development status?
Hi, Thanks for the offer. While it does not interest me (I'm into Mono as a hobbyist), it may interest others. For the record, Miguel replied to this message of mine, although it does not show on the mailing list. To sum things up, WinForms is now in the hands of the community, the Mono team will concentrate on other parts of Mono instead. Tom Hindle and myself have been appointed as maintainers, so we can review and push the patches of the community, including our own. And there's still room for more maintainers, if anyone is interested (if so, get in touch with Miguel)...

Re: [Mono-winforms-list] Removing the IDeviceContext.cs file
Hi Andy, Thanks for the answer. I think it was just some kind of internal class to replicate the behavior of the Drawing.IDeviceContext one, but since Drawing.IDeviceContext didn't exist in .NET 1.1, it was done internally in System.Windows.Forms, without exposing the class. That way, more code could be shared between 1.1 and 2.0, using 2 different classes as if it was the same one. I think we want to remove it, can't see why we'd want to keep it. Do you know if the only file reference I need to remove is in the System.Windows.Forms.dll.sources file, as I suspect?

[Mono-winforms-list] Quick question about bug 661750
Bug 661750 is about an exception when converting the value of a NumericUpDown control to hexadecimal, if the value is 0. This conversion happens in the UpdateEditText method of the NumericUpDown control. The author of the code added the following comments: // Decimal.ToString doesn't know the X formatter, and // converting it to an int is narrowing, so do it // manually.. It'd be possible to fix this conversion bug by updating the conversion code a little, but instead, Oliver proposes (in bug report 661750) that we do this instead: Text = ((Int64)dvalue).ToString(X, CultureInfo.CurrentCulture); Which seems right, as Int64.MaxValue is actually the maximum value of a NumericUpDown in hexa mode, not Decimal.MaxValue. So there would be no precision loss, actually. I support this suggestion very strongly, as that'd mean we'd replace 131 lines of code with a single one. Slimming down the NumericUpDown code from 615 lines to 485, and therefore avoiding more potential bugs. Does this seem alright? Oh, and while I'm here, do you prefer Int64 or long? I don't think I've seen that specified in the Mono guidelines. But from what I've seen int is more commonly used than Int32, so it'd probably make sense to go for long. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list
[Mono-winforms-list] Help fixing bug 661753 (cloning ToolStripItem objects)
See bug 661753: TreeNode clones aren't complete, some properties are missing.
This is the code I have so far (in TreeNode.cs):
public virtual object Clone()
{
TreeNode tn = (TreeNode)Activator.CreateInstance
(GetType ());
tn.name = name;
tn.text = text;
tn.image_key = image_key;
tn.image_index = image_index;
tn.selected_image_index = selected_image_index;
tn.selected_image_key = selected_image_key;
tn.state_image_index = state_image_index;
tn.state_image_key = state_image_key;
if (nodes != null) {
foreach (TreeNode child in nodes)
tn.nodes.Add ((TreeNode)child.Clone ());
}
if (context_menu != null) {
tn.context_menu = new ContextMenu();
foreach (MenuItem item in
context_menu.menu_items)
tn.context_menu.menu_items.Add
(item.CloneMenu ());
}
if (context_menu_strip != null) {
tn.context_menu_strip = new ContextMenuStrip();
//foreach (ToolStripItem item in
context_menu_strip.Items)
//tn.context_menu_strip.Items.Add
(item.Clone ());
}
tn.tag = tag;
tn.check = check;
tn.tool_tip_text = tool_tip_text;
if (prop_bag != null)
tn.prop_bag = OwnerDrawPropertyBag.Copy
(prop_bag);
return tn;
}
However, the problem is the commented lines for context_menu_strip: I can't
clone the ToolStripItem objects, as it has no clone method.
So, what would be the best way to clone the ToolStripItem objects? Do I have to
copy each property manually (as in here:
http://blogs.msdn.com/b/jfoscoding/archive/2005/09/28/475177.aspx)? Hopefully
not... If I have to, maybe I should make it an internal method inside
ToolStripItem, so other objects can reuse it...?
Thanks for the help.
PS: the original code used both private fields and public properties, but
mostly private fields, so I homogenized the whole thing and used private fields
everywhere (as I don't think it's necessary to run the property code in this
case). Maybe I should have used public properties instead... *shrugs*

Re: [Mono-winforms-list] RichTextBox Issues
I don't think so, but wouldn't mind being proven wrong. WinForms is not a high priority for the Mono team, so your best bet would be doing it yourself (or finding someone to do it), in my opinion. WinForms is implemented in C# in Mono, so the code is actually quite accessible. BrokenKingpin wrote: Thanks for the information, this at least lets me know the outstanding issues of this control.

Re: [Mono-winforms-list] Convert .Net Application To MAC OS
Best case scenario: you have nothing to convert, it works right away (without even needing to recompile). But if your program uses Windows-specific stuff (hard-coded Windows directory separators, upper/lower case mismatches in paths, native Windows DLL calls...) , you'll have to make some changes. You may also get into Mono-WinForms-specific bugs, or Mono-WinForms-Mac-only bugs.

Re: [Mono-winforms-list] Suffering from mono-noob-cleosis.
Hi, 1) Sure. However, note that WinForms is currently buggy on OSX, but the rest should work fine. Until there is a worthy WinForms driver for OSX, I suggest you use GTK# or Cocoa (through MonoMac, for example) instead, for example. Only consider WinForms on OSX if your app is simple enough. On a side note, it's possible to use an alternate X11 WinForms driver on OSX by passing a command line parameter (requires an X11 server install on the Mac), which apparently works better than the Carbon-based driver. (Sorry if this is all a bit confusing.) 2) It depends on what you do. If you just wanted to check out how your WinForms or GTK# app runs on OSX, there is no need to port anything, and no need to recompile either. But if you want to do OSX-specific code (like using MonoMac), then it's a different story. Also, some people want to have a custom UI for OSX (usually using some kind of Cocoa C# wrapper), which means more (duplicate, OS-specific) work, while others don't want to bother and are happy using a cross-platform GUI toolkit instead (which looks less good / native on OSX, but may still work fine). 3) I don't think there are any Mono books that are recent enough to be interesting. KurtPW wrote: Hi all:Completely new to Mono. I develope C#.Net Winforms apps and I'd like to try porting one to OSX. But before I jump in I have a few high-level questions for you all.1) For those of you who have run .Net on OSX, what were your results? Was it worth it?2) Where does one begin?

Re: [Mono-winforms-list] Suffering from mono-noob-cleosis.
Yes. Basically, MonoMac is a C# wrapper around native OSX libraries. An extra layer that lets you use them from the .NET side, in managed land. Also, note that MonoMac is quite recent, and isn't mature yet. Before, there were many different OSX wrappers for Mono (Monobjc, Cocoa#, etc), but no official one, causing division in the community. So, MonoMac is an attempt from the Mono team to fix that. Anyway, depending on what you want to do, you may not need to use MonoMac. If you don't need a strong Mac integration (using Mac-only features...), you can do without, I think. KurtPW wrote: Thanks Stifu:Yes, that is a bit daunting as I am not a Mac person.But if you want to do OSX-specific code (like using MonoMac), then it's a different story.

Re: [Mono-winforms-list] Clearing Textbox Controls
Hi, It is this bug: https://bugzilla.novell.com/show_bug.cgi?id=621475 I submitted a patch for it, but it hasn't been applied yet. scruffyruffian wrote: Hi, I apologise if this has come up before, I used the search but found nothing particularly relevant. I have an application written in C# .NET 3.5 which I'm trying to get running with Mono so that people using Linux can mess with it too. I have a text box which starts off with text in it, then when the user clicks, it uses the click event to remove that default text - allowing the user to enter their own without having to delete the default text manually. However, running under Mono (2.6.7), when I click on the text box control it clears the text, but the next click or keyboard hit will cause the form to just close. I tried creating a new Solution in VS2008, stuck a text box on the form. The only property I changed was the Text on the TextBox control which I changed to Hello. I then gave the TextBox control a Click event, and tried doing the following to try and clear the text box without causing the form to close unwontedly (not all at once - 3/4 were commented out at all times): textBox1.Text = ; textBox1.Text = string.Empty; textBox1.Clear(); textBox1.Text = null; However, all of these cause the form to simply close after clearing the text from the box. Interestingly - if I add something like this: MessageBox.Show(Hi); After the line for clearing the text box then the form doesn't close after clicking. It brings up the message box and then gives you the cleared text box to enter into what you wish, and remains usable. Am I the only one who experiences this behaviour? I'm not a professional developer, I'm just messing with it myself in the hope of learning something - so could it be that some practice on my part is causing my issues? Note: No error log is generated, the form appears to close as if you were trying to close it normally. (I believe for example, that it would trigger the form_closing event).

Re: [Mono-winforms-list] WinForms for OsX excessive delays in responding
Honestly, at the moment, I don't think WinForms on Mac can be used professionally... unless your project has hacks here and there to work around issues. WinForms on Mac is just too buggy (my app won't run because disabled controls still fire events...). But you could also use the X11 version [1], which should work better. Actually, you could try that to see if that solves your problem. [1] Forced through parameter, like: MONO_MWF_MAC_FORCE_X11=1 mono myapp.exe But requires X11 server installed. Scott Bolland wrote: Hi guys, I am having a little problem with using WinForms in OsX. I am using a timer to call the refresh method for drawing an animation. However, when this drawing is time consuming (i.e. if you maximise the window), there is a prolonged delay in handing a mousemove event. That is, although the animation is still running smoothly, it seems that the mousemove event is being buffered and responded to some time later. I have attached the given project below. Any assistance would be greatly appreciated, as I would love to use mono for some professional projects I am working on, but can't seem to get around these features Cheers, Scott http://mono.1490590.n4.nabble.com/file/n2289437/winformsVBiKnow.zip winformsVBiKnow.zip -- View this message in context: http://mono.1490590.n4.nabble.com/WinForms-for-OsX-excessive-delays-in-responding-tp2289437p2289445.html Sent from the Mono - WinForms mailing list archive at Nabble.com. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list

The reason I didn't specify how to do this is that I don't know myself. :) I think it should happen by default if your installation is right, otherwise, it's probably a command line flag or something.

What are the problems? Do you have exception messages? You can run applications doing mono appname.exe --debug to have more information. It's possible they're simply bugs and that you have nothing else to install.

On Windows, follow these steps: 1- Launch the Mono command line 2a- Type something like: macpack -n:c:\monotext\form1.cs -a:form1.exe -o:. -m:winforms 2b- Or if it doesn't work (not sure if you need double quotes around the path or something), try browsing to the right directory first (ie: c:\monotext\), then just do: macpack -n:form1.cs -a:form1.exe -o:. -m:winforms For more details on macpack: http://www.go-mono.org/docs/index.aspx?link=man%3Amacpack%281%29 http://www.theevilboss.com/2009/06/using-mono-for-net-development-on-mac.html Starting to get somewhere!

Re: [Mono-winforms-list] New Winforms in Daily Snapshot?
Simple question: do I get the updates to the Winforms if I build from the Mono Daily snapshot? My guess is that I do. Yes. Also: can I update just Winforms, or does that make no sense? Sometimes yes, sometimes no... It depends whether some dependencies changed over the time. It could be that you have more DLLs to update. By the way, the easy way to update WinForms might be to look around Novell's bugzilla: Ivan has been posting the SVN WinForms DLL (compiled at the posted date) in a few bug reports.

Re: [Mono-winforms-list] Some Winforms Questions
Hello, 1) I think there's no solution for that, it's been asked before, you may want to look around. 2) Mixing GTK# and WinForms, although more or less possible, is not a good idea, IMO. Just pick one or the other. 3) No idea. 4) There hasn't been any Mac-specific progress that I could see (there were some plans for Mono 2.6, but they ended up being scrapped, unfortunately). That said, I recently discovered a parameter that makes WinForms apps behave better on Mac. Launch your app by typing: MONO_MWF_MAC_FORCE_X11=1 mono yourapp.exe and see if some things behave better... 5) WinForms support for iPhone or Android isn't planned. What the Mono devs are opting for is using wrappers around the iPhone / Android UI libs, rather than reusing desktop API like WinForms or GTK#. This has the benefit of really looking native, at the cost of having to write platform-specific code. 6) Dunno. Daniel Rosenstark-4 wrote: Some simple questions about Winforms on OSX. I should note that I had given up on my app as being Windows only, but when I tried the port to Mono Winforms I was totally amazed at how complete it is. 1) My app is running on Winforms on Mono nicely (well, 90% of it), but I cannot take over the app menu bar like a native app. It says Mono with the Apple to the left. Is it possible to take this over? I do NOT want to run in a full-screen exclusive mode. 2) If #1 is not possible, it seems GTK# apps can do this. Is it possible to put my app inside a GTK# app in other words, are the two technologies mixable? 3) The RichTextEditor in Winforms on Mono is mostly useless. Does GTK# provide something better? Or can anyone recommend any libraries for Winforms? I actually don't need richtext, but I do need undo, hyperlinks, indenting and bullets 4) There were some initial problems with Snow Leopard and Mono Winforms. Have they all pretty much been resolved by now? 5) What is the present/future of Winforms on Mono for IPhone? Android? 6) I see this link for uninstalling and installing Mono on OSX ( http://www.mono-project.com/Mono:OSX). What's the best way to update an installation?

And about point 2, I read an article (http://social.msdn.microsoft.com/Forums/en-US/winforms/thread/aaed00ce-4bc9-424e-8c05-c30213171c2c) that gives a tip to fix that, which works but introduces drawing problems with my double-buffered Panels (not to mention that with my application, it triggers an exception using Mono). On a side note, the flickering isn't as bad with Mono, it's bearable. So, in the end, rather than fixing these TabControl issues, I'm starting to think using a custom TabControl (which I guess shouldn't inherit from TabControl to avoid the issues above, but directly from UserControl) is the way to go. Is there a free and open-source custom TabControl that does this? And Mono friendly, ie: no P/Invokes. I need no extra functionality other than that. PS: that kind of issue makes me think GTK# would probably be less annoying to work with. :D But for this particular project, I'd like to keep using WinForms. -- View this message in context: http://www.nabble.com/TabControl-issues...-Looking-for-a-nice-custom-TabControl-tp24144245p24144245.html Sent from the Mono - WinForms mailing list archive at Nabble.com. ___ Mono-winforms-list maillist - Mono-winforms-list@lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-winforms-list
