I am trying to make a tree view in Gtk3 such that each row has the size of two rows of text. The following is a minimal working example:

In Rhythmbox (GNOME's music player), when it's playing music, you can open the notifications panel and control the music playback from there. Here's a screenshot. The playback controls are bordered in orange; they have a little music note icon:

This is what I want to make; the media playback controls. Note that, while it is in the notifications panel, it's not technically a notification, because it never pops up on the screen, and you can't make it go away. In the screenshot, you can see the actual notification, which I don't want to make, below the controls.

I know that there's a Gio.Notification, but it's not quite what I need (unless I'm very much mistaken). I searched in Gio, Gdk, and Gtk, but I didn't find anything. I also searched, among other things, [gtk] media control and [gtk] media notification on Stack Overflow, but I didn't find anything there either.

Thanks to the help of BobMorane, I've now figured out that Rhythmbox uses libnotify for its player controls. I know how to create actions using Notify.Notification, and I can make them have images, etc., but what I still haven't figured out is how to:

1. Make the notification so that it can't be closed;
2. Make it so that the action buttons are next to the icon and text, not under;
3. Keep the notification on top of all the others in the notifications panel.

Using Python's help() function to look at gi.repository.Notify.Notification, the only methods I see that seem to have potential are add_action() (particularly its user_data parameter) and set_hint() (and its variants). Could these be used to achieve my goal?

How do I make a media-control "notification" in Gtk with Python, as explained above?

This should be a no-brainer but I just can't seem to figure it out. If I build a Gtk.PopoverMenu:

How can I make a gtk4::Box clickable in gtk_rs?

In GTK3 it seems that using an EventBox was the way to achieve this, however in GTK4:

Stop using GtkEventBox

GtkEventBox is no longer needed and has been removed.

All widgets receive all events.

https://docs.gtk.org/gtk4/migrating-3to4.html#stop-using-gtkeventbox

So it seems that click handlers should now be attached to widgets directly. However I can't find any clear documentation or examples on how to do this.

If someone could give me an example of attaching a click listener to a gtk4::Box it would be much appreciated.

i write a code for calculator in gtk3 c the code is total numbers, in i write 1+1+1+1 the result is 3+1 i want to fix to 4 calcul result

in i write sprintf(result,"%d%s",temp,rest); the result for 1+1+1+1 is 3+1 i want to result 4 i check for sprintf(result,"%d",temp); is not correct.

the code of application :

Is there a way in gtk to make an eye icon on the right of an entry to show a password? I know there is a way to make a checkbox under an entry to show the password, but I want the button to be inside the entry, not outside. To put it simply:

What i'm looking for is this: show password icon

...and not this: show password checkbox

Please think before you dislike because it literally only takes ~20 to permenantly ban a year-long user. If anyone has enough reputation to edit the question and add the images in, please do)

I'm trying to draw on a window with Gtkmm for C++, cairo::context, gdk::pixbuf. I've noticed that for some widths (in my example 298), instead of my image, I get some horizontal black lines (alternated with white stripes).

For other widths (in my example 300) I get a normal image. (I'm just drawing a yellow background in my example).

What am I doing wrong ? How can I obtain to draw correctly for any image width ?

I'm finding this behavior both on :

windows 10 / msys2 / gcc11.2 / std=c++20

opensuse 15.2 / gcc 11.2.1 / std=c++17

and on both I have library versions:

Here's my code:

On Windows package org.eclipse.swt.win32.win32.x86_64 is used, while for Linux build it's org.eclipse.swt.gtk.linux.x86_64.

1. If nothing is specified in module-info.java, error message is java: package org.eclipse.swt does not exist

2. If in module-info.java both are specified:

I am trying to add items to the context menu of a TextView in GtkSharp (version 3.22.25.128). The context menu normally has the entries Cut/Copy/Paste/Delete/Separator/Select All/Insert Emoji. I am trying to add several more entries to the menu, starting with a separator.

To do this I am adding a handler to the PopulateMenu event, like so:
