问题 I'm using a Gtk3 TreeView that looks like above. The model is a Gtk.TreeStore Gtk.TreeStore(str, GdkPixbuf.Pixbuf) For the picture I could add to the model the correctly sized images via: pixbuf.scale_simple(48,48,GdkPixbuf.InterpType.BILINEAR) However I'm also using the model elsewhere showing the pixbufs in a different manner and the pixbufs can also be a variety of sizes. What I would like to do is force the size of the picture displayed at run-time. The question is - how do I do that? I

问题 I'am working on GTK in python after creating a CheckButton or Button with: x = Gtk.CheckButton() y = Gtk.Button("Config") I want to check type of x or y When use type() it returns <class 'gi.repository.Gtk.CheckButton'> or <class 'gi.overrides.Gtk.Button'> Is it possible to check It's type in another way ? 回答1: The idiomatic way to check if a variable is an instance of a specific type is using isinstance() , e.g.: >>> import gi >>> gi.require_version('Gtk', '3.0') >>> from gi.repository

问题 Am working on the project in which am required to fetch files from the server and to display them on the client post.All of this is to be done in the UNIX environment where I used C language for coding client and server and GTK+ for the interface which will display files in the PDF format. My problem is I do not know how can I intergrate a PDF viewer in such interface.

问题 Context In GTK 3, people can set their own themes. Even the default theme (Adwaita) is provided with two variants: a light one and a dark one. As I am writing my own widget (in python), I need to get these colors in order to avoid drawing black on black or white on white. Question How can I access the default colors of the user GTK theme? Things that don't work GtkSettings used to provide an acceptable gtk-theme-color property, but it is not there anymore and there is no reference in the doc

问题 I want to make select rows of a PyGTK Tree-view (coupled to a List Store) un-selectable and if possible,greyed out. Is there a way to do this? 回答1: This is a bit hackish minimal code, but it will make it impossible to select the middle row ('B'). If you wish that the previous selection should be remembered it ought to be quite easy to just store which rows are selected at the end of the signal-callback and overwrite current selection if a bad row was selected. As for the individual rows and

问题 I write in Android Studio on Windows. And I use OpenCV in my native c++ code.When calling the function, I get this error in logcat: "OpenCV Error: Unspecified error (The function is not implemented.
