Re: [Gambas-user] Resize event...
Stephen Bungay ha scritto: Well, after much consultation with Benoit I finally understand what is going on and how to get around the problem. For the benefit of anyone else who has been reading this thread, Doraino and I were talking about instantiating a form inside a container on another form and resizing that embedded form when the parent is resized. In a nutshell the solution is to reference the instantiated form by it's handle reference, created at the time of it being instantiated, and NOT by its' name. For example, consider an application that has three form classes, FormMain, FormX, and FormY. Form Main will contain a tabstrip and inside that tabstrip we want to instantiate FormX on tabstrip index 0 and FormY on tabstrip index 1. When we resize FormMain we want the embedded forms in their tabs to resize appropriately. Our FormMain Class logic might look like this; ' Gambas class file Private mFormInitialized as Boolean Private mhFormX As FormX Private mhFormY AS FormY Public Sub Form_Open() InitializeControls End Private Sub InitializeControls() TabStrip1.Index = 0 mhFormX = New FormX(TabStrip1) TabStrip1.Index = 1 mhFormY = New FormY(TabStrip1) TabStrip1.Index = 0 mFormInitialized = True End Public Sub Form_Resize() With TabStrip1 .Width = .Parent.width - 10 .Height = .Parent.height - 20 mhFormX.Resize(TabStrip1.Width - 10, Tabstrip1.Height - 10) mhFormY.Resize(TabStrip1.Width - 10, Tabstrip1.Height - 10) End With End The resize events in the forms referenced by mhFormX and mhFormY will now fire as expected, the embedded forms resize events will now fire as expected. Steve. Something strange is happening now. I remember something wrong when embedding forms in tabstrip, for sure, and proof is you encounter the same problem. But yesterday I tried again to embed, and I found nothing wrong - both resize and open event were called in the embedded form (resize event was a little slower when embedded, but who cares). I tried both QT and GTK. I never changed my version of Gambas, which is 2.0.0, so it is not a version issue. The only wrong thing is that a mhFormY = New FormY(TabStrip1) as evformy doesn't work, and an observer is needed. Now we come to your source. The mFormInitialized variable serves what purpose? Then, where is the point to explicitly resize FormX and FormY in a manner so convolute? At the time the form is instanciated, it could be resized - so a single routine can be used to open as many forms are needed. Next, who says that FormX wants to be resized to its container.width-10 and container.height-10? When I say independence, I mean that FormMain has to embed another form, without knowing what that form will do with its geometry. If the explicit call to FormX.resize() has only the purpose to raise a resize event, well - I understand: when the resize event fires, the embedded form can do whatever it wants. But for me, the resize event was firing without any special processing. All this seems messed, but I have a solution/request. How about an extended syntax to RAISE, which permit to send an event to a specified object? Like this: RAISE resize TO mhFormX If the TO keyword is not specified, the event is sended, just like now, to the parent object. Anyway, this should be not needed in this case - I repeat - for me the embedded forms receive form_open and form_resize - still I am sure that there was something wrong, but can't remember what... This evening I will send my test project, if anybody can care.

[Gambas-user] Centos? x86_64 vs i386? GTK vs QT?
Hello folks! I installed Gambas2 about two hours ago and have been sitting here in awe since then. To say that I'm impressed would be an understatement, and I'm truly looking forward to playing with this wonderful toy. I have three fairly basic questions (so far) and hope you will bear with me while I try to get up to speed here: First, while my personal desktop and development machine currently runs Fedora 9/x86_64, I maintain some Centos 5/i386 application servers. I would like to be able to develop stuff on my machine here and copy it to the application servers and have it just work if I can. Gambas creates something that the file command tells me is a gbr2 script text executable when you tell it to make an executable, and that script depends on gbx2. Is there a difference between a gambas-created executable made on an x86_64 machine and one made on an i386 machine? Can I create an executable with gambas2 on my x86_64 machine and expect that it will just-work on an i386 box? Related to this, while gambas2 lives in the standard Fedora 9 repository, I haven't yet found a gambas2 i386 rpm for Centos 5. Is there one available for downloading somewhere that I haven't looked yet, or do I have to compile that myself? And if I have to compile it myself, what's the easy way to do that? Could I just grab a .src.rpm from somewhere and run rpmbuild--rebuild on a Centos box? And thirdly, is there a practical difference between a QT and a GTK gambas project? My hello world looks pretty much the same regardless of which option I pick. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com DRY CLEANER BUSINESS FOR SALE ~ http://www.canadadrycleanerforsale.com - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user
Re: [Gambas-user] Resize event...
Now we come to your source. The mFormInitialized variable serves what purpose? mFormInitialized is a hold over from something I used to do in VB, and ocaisionally find useful in Gambas, so I just never removed it. Call that a force of habit. It has proven useful allowing the Initialize Controls subroutine to behave differently based on the value of the boolean flag. Then, where is the point to explicitly resize FormX and FormY in a manner so convolute? At the time the form is instanciated, it could be resized - so a single routine can be used to open as many forms are needed. Actually it is resized at the time it is instantiated. What were doing here is making sure that the embedded forms that we want to resize actually do resize. Next, who says that FormX wants to be resized to its container.width-10 and container.height-10? When I say independence, Um... not to put too fine a point on it but the one who says that a form 'wants to be resized is the programmer, purely their judgement call, and no one else's. The programmer is the one in control, if he/she doesn't want FormX to be resized then simply don't call the resize method. If he/she wants to resize it to container.Width-50 them by all means do so. It is up to them. Full stop. I mean that FormMain has to embed another form, without knowing what that form will do with its geometry. If the explicit call to FormX.resize() has only the purpose to raise a resize event, well - I understand: when the resize event fires, the embedded form can do whatever it wants. But for me, the resize event was firing without any special processing. Yes, the point is that the embedded form can do whatever it wants, but it basis its' actions on what form main has done. Therefore the embedded form can be loosely coupled to it's host, passing information back and forth via properties and events. All this seems messed, but I have a solution/request. How about an extended syntax to RAISE, which permit to send an event to a specified object?

This evening I will send my test project, if anybody can care. I'd be interested in learning your results and, although I'm no guru, perhaps I might see something you miss,... and of course it works the other way around... you might see something I've missed. Certainly if you had not replies to my initial email I might not have started talking to Benoit and would still be flailing about. Community helps.

I was also concerned because the update said that it wanted to remove those Gambas programs that I have developed myself, and installed using synaptic so that I can update them as I go. I assume that I will have to recompile and reinstall those packages? If your packages depend on a concrete version, you should at least update Debian Package information a rebuild them, yes. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Gambas-user mailing list Gambas-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/gambas-user

Then, where is the point to explicitly resize FormX and FormY in a manner so convolute? At the time the form is instanciated, it could be resized - so a single routine can be used to open as many forms are needed. Actually it is resized at the time it is instantiated. What were doing here is making sure that the embedded forms that we want to resize actually do resize. No, it is not so - and, your way could be more correct. The children forms are first instanciated - stop. Then, when a Form_resize event arrives for the main form, the main form resizes the children forms. So we are both wrong... :- Your way could be more correct, or mine... it depends on the logic of program and other things, like the order initial events are sended to forms. Next, who says that FormX wants to be resized to its container.width-10 and container.height-10? When I say independence, Um... not to put too fine a point on it but the one who says that a form 'wants to be resized is the programmer, purely their judgement call, and no one else's. The programmer is the one in control, if he/she doesn't want FormX to be resized then simply don't call the resize method. If he/she wants to resize it to container.Width-50 them by all means do so. It is up to them. Full stop. I wrote a sort of MDI application, where the MDI (children) forms are not walking in the main window but instead are put inside a tabstrip (the same as you). There are four or five different form types, and there can be multiple instances of the same form (with different data). At any given moment, the tabstrip can have 1 tab, 2, or 8 (there is a limit). So, in the resize event of the main form, I don't want to call each children form. I want that the embedded forms receive a resize event if, and only if, they are resized. If my main form is resized, but my tabstrip is not, then the children form should not be resized. If my main form has two tabstrips - one expanding and the other not, then things get more complicated. I don't want to be in control for everything, where should be mechanisms to do the work in place of me. I mean that FormMain has to embed another form, without knowing what that form will do with its geometry. If the explicit call to FormX.resize() has only the purpose to raise a resize event, well - I understand: when the resize event fires, the embedded form can do whatever it wants. But for me, the resize event was firing without any special processing. Yes, the point is that the embedded form can do whatever it wants, but it basis its' actions on what form main has done. Therefore the embedded form can be loosely coupled to it's host, passing information back and forth via properties and events. Passing information through properties and events? I had a lot of problems with it... I think embedding a form inside a tabstrip makes sense if you have many of them, dynamic. If it is not so, then why not copy and paste controls from a tabstrip page to another, and voilà? With dynamic forms, problem is when a form chooses to close. How to close the hosting tab?... All this seems messed, but I have a solution/request. How about an extended syntax to RAISE, which permit to send an event to a specified object? Like this: RAISE resize TO mhFormX If the TO keyword is not specified, the event is sended, just like now, to the parent object. I can see where that would be useful for raising events that can not be raised any other way. With the resize event we can raise it simply by calling the resize method, so that is not a good example. There is a lot of difference, indeed. A raise event only tells to the destination form you have been resized; please check. Calling its resize method simply resizes the form and does not tells you have been resized. If you choose to resize the destination form, then you override its logic. If you send it an event, you use its logic. This is different... More about this. If a form receives a resize event, and decides to resize itself, then a new resize event is fired, which causes the form to be resized, which unleash another resize event... stack overflow! So you can not resize a form inside its resize event handler... or what? I will investigate on this too. Anyway, this should be not needed in this case - I repeat - for me the embedded forms receive form_open
[Gambas-user] Bug: in gb, net socket client code in combination with gb.qt

I was driving me nuts. Then I got a lightbulb moment telling me that QSocketNofifier is a QT thing, so if you change ClientSocket to use component gb.qt instead of gb.gtk, it has the same bug!!
