Checkbox With Css In Glade Python
everyone I am trying to change the colors of the checkboxes when they are pressed because I am doing a job that requires their use. I am using them with no 'Drawing Indicator' attr
Solution 1:
Since the Gtk.CheckButton is set without draw indicator, then it basically becomes a togglebutton and the CSS class, on Gtk+ 3.18 is .button.
Defining a provider for this class and adding it to the screen it's rather simple.
First, the relevant css code is:
.button:checked {
color: white;
background: red;
}
For this example, the button, when checked, will have a red background with white text.
A working example would be:
#!/usr/bin/python3from gi.repository import Gtk, Gdk
import sys
classMyWindow(Gtk.Window):
def__init__(self):
Gtk.Window.__init__(self, title="Hello World")
self.set_name('MyWindow')
self.set_default_size(600, 300)
self.box = Gtk.HBox()
self.box.set_halign(Gtk.Align.CENTER)
self.box.set_valign(Gtk.Align.CENTER)
self.add(self.box)
self.button1 = Gtk.CheckButton(label="1")
self.button1.set_mode (False);
self.button1.connect("clicked", self.on_button1_clicked)
self.box.pack_start(self.button1, True, True, 0)
self.button2 = Gtk.CheckButton(label="2")
self.button2.set_mode (False);
self.button2.connect("clicked", self.on_button2_clicked)
self.box.pack_start(self.button2, True, True, 0)
defon_button1_clicked(self, widget):
print("Button 1")
defon_button2_clicked(self, widget):
print("Button 2")
defmain(argv):
defgtk_style():
css = b"""
.button:checked {
color: white;
background: red;
}
"""
style_provider = Gtk.CssProvider()
style_provider.load_from_data(css)
Gtk.StyleContext.add_provider_for_screen(
Gdk.Screen.get_default(),
style_provider,
Gtk.STYLE_PROVIDER_PRIORITY_APPLICATION
)
gtk_style()
win = MyWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
if __name__ == "__main__":
main(sys.argv)
The result is something like this:
This will apply the same behavior to all checkbuttons, so if the idea is to use this solution only on those numbered buttons but want another checkbuttons (as togglebuttons) on the application then you need to add/remove a style class or add a custom style class, etc.
EDIT: Solving the question code not working.
The problem resides on the fact that gtk_style () is not being invoked. The call is inside its own definition:
defgtk_style():
...code...
gtk_style() # <----- Here is the problem.Python indentation is relevant. The way it is now, it becomes recursive and it's not being invoked. The solution is to remove that line and move it to the code below, following the, e.g., window.connect line.
