GtkTextBuffer stripping carriage returns?
I've got a GtkTextBuffer, and I'm pasting some text that contains a carriage return in it (e.g., \r\n). I know for sure that there's an \r\n in it because when I copy the text from the buffer into a hex editor, it shows the \r\n is there. However when I get the text from the buffer (gtk_text_buffer_get_text), the \r isn't there... just the \n. Any idea why this might be? ___ gtk-list mailing list gtk-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-list
Screenshots using GTK+ on Windows: works fine except if monitors are stacked vertically.
I use GTK+ to take screenshots in my program on Windows. It works great; however, someone reported to me that if their monitors are stacked vertically, the monitors in the top row aren't included in the screenshot properly (it looks garbled). I was able to confirm this; I opened up my graphics driver's control panel, positioned my secondary monitor on top of the main one in the configuration, took a screenshot using my program, and while the main monitor (positioned on the bottom) shows up fine in the screenshot, the secondary monitor (positioned above the main monitor) shows up garbled. I'm not sure if this is a bug with my program (is there more than one window besides the root window?) or with GTK/GDK. Any help would be appreciated. By the way, I already submitted this as a bug (#634713), and you can view it, along with an example program demonstrating the issue, here: https://bugzilla.gnome.org/show_bug.cgi?id=634713 ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
Re: Give keyboard focus to GtkMenu
I discovered that if my application's main window is focused when I pop-up the GtkMenu anywhere on the screen, the GtkMenu also has keyboard focus and can be navigated using the keyboard keys. However, if my application's main window does _not_ have focus, that's when the menu doesn't receive keyboard focus and can't be navigated using the keyboard, though this is what I'm trying to accomplish: keyboard focus to a GtkMenu even if the main window isn't in the foreground and doesn't have focus. I'm popping-up a GtkMenu at random coordinates on the screen (outside of my application's main window). I'd like to give keyboard focus to this GtkMenu. Since I'm using Windows, I tried: SetForegroundWindow(GDK_WINDOW_HWND(menu-window)); But that causes the menu to immediately disappear, as does: SetFocus(GDK_WINDOW_HWND(menu-window)); I also tried: GTK_WIDGET_SET_FLAGS(menu, GTK_CAN_FOCUS); gtk_widget_grab_focus(menu); But that doesn't do anything at all. Any ideas? I'm trying to make it so that the user can navigate the menu using their keyboard. ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

A better way of resizing GtkTreeViewColumns... but how do I do it?
Hi all, I'm trying to create GtkTreeViewColumn resizing functionality like how it is in Thunderbird. Key word here is trying. So far I haven't succeeded. The easiest way to understand how this resizing works is to fire up Thunderbird and play with resizing the columns yourself, but basically the way it works in Thunderbird is if you drag, say, column #1 to the right, this increases the width of column #1, at the same time decreasing the width of column #2 by the same amount. This happens until column #2 reaches its minimum width (for example, 0 pixels). At this point, continuing to drag column #1 to the right still increases the width of column #1, but since column #2 cannot be shrunken any further, then column #3 is shrunken until it reaches its minimum width. This continues until all of the columns to the right of column #1 are at their absolute minimum widths; at this point, column #1 can't have its width increased anymore, so continuing to drag the column to the right does nothing. While the mouse button is still held down, if you were to start dragging column #1 to the left again (to shrink it), what would happen is what happened above, except in reverse order. As column #1 shrinks, the last column in the tree view grows until reaching its width at the time the original drag (when the mouse was first pressed down to start the drag) first started. At this point, the second to last column grows until reaching its width at the time of the original drag... and so on. Then of course, when column #1 reaches its minimum width, column #0 shrinks until it reaches its minimum width. Since column #0 is the first column, then continuing to drag column #1 to the left won't shrink it anymore; in fact, nothing will happen. One of the major benefits to handling dragging like this is: the columns will never be resized out of bounds and cause the GtkTreeView to grow in width or, if the GtkTreeView containing the GtkTreeViewColumns is packed into a scrolled window, cause horizontal scrollbars to appear. Having these scrollbars appear, or the tree view grow in width (and thus increase the width of the window) is super annoying for the user and makes things look a lot less clean. Which is, I assume, why Thunderbird handles it this way, as do other applications. So, anyway, my problem is that I just can't figure out how to do this in GTK+. I'm wondering if it's even possible? If it is, would someone be able to create a working example for me? I'd be willing to pay for this if necessary. As far as I know, the only signal you can connect to to know if a GtkTreeViewColumn has been resized is the notify::width signal. Problem is, you can't return TRUE or FALSE from the signal handler function to tell GTK+ not to allow the resize to go through. It's just a notification signal. So that prevents me from, for example, detecting that all columns to the right of the one being dragged have reached their minimum widths and then telling GTK+ to stop the column from having its width increased anymore. Another problem: if you call gtk_tree_view_column_set_fixed_width() -- what I am doing is calling gtk_tree_view_column_set_resizable(column, TRUE) and then calling gtk_tree_view_column_set_sizing(column, GTK_TREE_VIEW_COLUMN_FIXED) when creating the columns, by the way -- within the notify::width signal, it creates an infinite loop, which I don't know how to prevent, either. Again, any help would be much appreciated. Thanks! ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
Re: GTK+ 2.20.0 is now available for download...
Out of curiosity, how is Win32 support? I know that the MS-Windows theme wasn't working with 2.18 (client-side windows support needed to be added), and that on GTK.org it said that 2.16 was in a way more stable than 2.18 on the Win32 platform. Has this changed? I see that in the release notes it says XP themes have been disabled since they don't work but I'm not sure if that has anything to do with the MS-Windows theme or not. ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
GTK+/pango 32-bit on Windows 64-bit
Is anyone aware of any issues running GTK+ and/or pango 32-bit on Windows 7 64-bit? Unfortunately I don't have 64-bit hardware at my disposal to test this on, but someone who's trying to use my app is reporting that when they run it, they get: libpango-1.0-0.dll is either not designed to run on Windows or it contains an error.

GTK+ 2.16.6 Win32 dependencies...
I just upgraded my binaries on Win32 from 2.16.4 to 2.16.6, and noticed that now my GTK+ app asks for libfontconfig-1.dll, libexpat-1.dll, and freetype6.dll at startup, whereas before it didn't need those DLLs.

Re: State of Gtk+-2.18 On Windows
The ms-windows theme engine doesn't work nicely in GTK+ 2.18, so I don't include it in the binaries above. This is unfortunate. This is a problem in the ms-windows theme engine code, it needs to be modified to work with client-side windows. Dang, that's a shame. Any idea on how difficult it'd be to modify the ms-windows theme engine code to make it work, and do you happen to know if anyone is currently working on this? - Patrick ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list
Manipulating a GtkComboBox like a GtkTreeView.
I've got a GtkListStore as the model for a GtkComboBox. I'd like to be able to call gtk_tree_view_set_show_lines() and gtk_tree_view_expand_all(), but obviously a GtkComboBox is not a GtkTreeView...
