I am writing a small python GTK application in which I have a drawing area that I am trying to "populate" using Cairo, which is a library I never used before (so bare with me if the answer is obvious and I did not see due to inexperience). What I am trying to achieve is using an SVG image as part of my drawing (if I got Cairo naming rig...
To scratch a personal itch, I'm writing something like a cross between a character map and an on-screen keyboard. When the user selects a character, I'd like to insert it into another application, specifically, the application that would next receive focus if my application were closed. Is there any way to do this? Right now, I work arou...
Hello! I write the simple example with gtk.FileChooserDialog. It works fine, but there is one problem under WIndows: I see '\' in first button instead of real drive names, such as 'C:\', 'D:\' and so on. I explored FileChooserDialog structure and tried to change '\' by real drive name, but it works unstable. Can anybody help me? import ...
I was attempting to mess with the style of a Button, and noticed that my changes were making the button look strange. To make sure I was doing the right thing, I tried doing what I thought would be semantically a no-op: button.set_style(button.get_style()) However, the button style changes dramatically after this line. I'm on Windows ...
What's the best way to indicate on a GTK interface that a button should be pressed / to "highlight" the button? The use case is that I have a set of checkboxes representing various settings, but for them to take effect, they must be submitted to a server. I want to indicate that the currently checked settings have not been sent to the se...
Which is the best and fastest way to retrieve the color of a given pixel of a widget? For example: I load an image onto a Gtk::DrawingArea or draw something on it. Then I try to retrieve the color of the pixel that the mouse cursor is over. I use this technique: bool MainWindow::on_canvas_motion_notify(GdkEventMotion* event) { get_...
I'm looking for a widget along the lines of GtkExpander, but for wxWidgets. Can't seem to find anything obvious in the documentation. Custom widgets (non-GPL) from somewhere else would be fine, but they need to work on Windows (i.e. without GTK). Practically (if it makes any difference) this is primarily for wxPython, on Windows and hop...
I want to detect whenever the selection of my gtk.TreeView changes and, when it does, to call a function w/ this information. The only way I've found to do it so far is to attach to all these signals: ... self.sitterView.connect("cursor-changed", self.selectionChanged) self.sitterView.connect("unselect-all", self.selectionChange...

I would like to have a GtkTextView in my (Python) program which shows text with the system monospace font. I found many ways which use an expicit font family name and size. However, I would like to use the system specified monospace font (e.g. from the ubuntu font preferences panel). My program should be able to run on Windows as well a...
This is sort of a strange question, but oh well. I feel like writing a (rich) text editor mainly to be used for note-taking, in either C or C++, using most probably GTK or Qt for the UI. The problem is that I can't really decide what to use. I know both C and C++, C a little better. I've never used Qt but I'm completely fine with learn...

So I have this TreeView/TreeStore, which I fill with data from a list. My application uses only said list as reference data. The TreeStore is just constructed for display. And the TreeView can be resorted by tipping the column headers. Because .set_sort_column_id() was used for initialization of each column. Problem is, following code a...
I'm interested in writing a Gtk application that uses an embedded SVG canvas for graphics, and I'm wondering what the current state-of-the-art is for using SVG in Gtk. I know that it's possible to embed Webkit inside of Gtk, and so that seems like one approach, but I would like to add interactivity to DOM elements in the embedded SVG can...
Hi, I have problem while adding a child to a GtkVBox. The VBox is inside a GtkViewPort which is inside a ScrolledWindows. After the child it's added using gtk_box_pack_end I check if it's really added checking the GLIST and it appears that it's added. Although visually anything appears and the scrolled window gets really big. Like if...
I am using Glade-3 to build a suite of Gtk applications. The applications are supposed to have a common look-and-feel, and we have decided on a common "frame" that all apps will share, that includes a menu bar, toolbar, status-bar(s), a vertical panel - and a space in the middle that will be filled out by each application. This common ...

Writing code or using the .glade files generated by glade? Which is better to use? libglade or gtkbuilder? Why is using the build option in glade2 discouraged? ...
