Gtk: Prevent vertical resizing of GtkWindow

Question

I can’t find how to do this :( gtk_window_set_resizable is there, but it disables resizing altogether, and I still want my window to be horizontally resized. Any ideas?

Answer 1

I believe you can try using the gtk_window_set_geometry_hints function and specify the maximum and minimum height for your window. In this case, you still allow the width to change, and the height remains constant. Pls check if the below example will work:

int main(int argc, char * argv[]) { gtk_init(&argc, &argv); GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL); GdkGeometry hints; hints.min_width = 0; hints.max_width = gdk_screen_get_width(gtk_widget_get_screen(window));; hints.min_height = 300; hints.max_height = 300; gtk_window_set_geometry_hints( GTK_WINDOW(window), window, &hints, (GdkWindowHints)(GDK_HINT_MIN_SIZE | GDK_HINT_MAX_SIZE)); gtk_widget_show_all(window); gtk_main(); return 0; } 

hope this helps, believes

Here is my GTK implementation #

 public static void SetFixedDimensions ( Window window, bool vertical, bool horizontal) { int width, height; window.GetSize(out width, out height); var hintGeometry = new Gdk.Geometry(); hintGeometry.MaxHeight = vertical ? height : Int32.MaxValue; hintGeometry.MinHeight = vertical ? height : 0; hintGeometry.MaxWidth = horizontal ? width : Int32.MaxValue; hintGeometry.MinWidth = horizontal ? width : 0; window.SetGeometryHints(window, hintGeometry, Gdk.WindowHints.MaxSize); }

Based on @serge_gubenko's answer, if you want to prevent vertical resizing only after the initial layout, you will need to set up a callback for the size-allocate .

Example:

 static gint signal_connect_id_cb_dialog_size_allocate; static void cb_dialog_size_allocate (GtkWidget *window, GdkRectangle *allocation, gpointer user_data) { GdkGeometry hints; g_signal_handler_disconnect (G_OBJECT (dialog), signal_connect_id_cb_dialog_size_allocate); /* dummy values for min/max_width to not restrict horizontal resizing */ hints.min_width = 0; hints.max_width = G_MAXINT; /* do not allow vertial resizing */ hints.min_height = allocation->height; hints.max_height = allocation->height; gtk_window_set_geometry_hints (GTK_WINDOW (window), (GtkWidget *) NULL, &hints, (GdkWindowHints) (GDK_HINT_MIN_SIZE | GDK_HINT_MAX_SIZE)); } int main(int argc, char * argv[]) { gtk_init(&argc, &argv); GtkWidget *window = gtk_window_new(GTK_WINDOW_TOPLEVEL); signal_connect_id_cb_dialog_size_allocate = g_signal_connect (G_OBJECT (state->dialog), "size-allocate", G_CALLBACK (cb_dialog_size_allocate), (gpointer) NULL /* user_data */); gtk_widget_show_all(window); gtk_main(); return 0; }
