ABDUL ZAGIROV reported a new bug.
Summary
-------
Icon does not appear in tray
Type : Bug
Priority : Low
Gambas version : Unknown
Product : GUI components
Description
-----------
Hi, everyone!
Not long ago I developed a sniffer of "rogue" dhcp servers using Gambas.
Everything works like a charm except for TrayIcon component.
I tried the following steps:
1. Selected necessary component in Projects > Properties > Components >
gb.gui.trayicon
2. Moved a TrayIcon element to the main form
3. Set suitable image for Picture property
4. Set Visible property to true
5. Started application
The application starts but there is no icon in tray.
Tried both 3.8.4 and 3.9.2 versions of Gambas. No icon!
Tried both 32 and 64 bit architectures. No icon!
Tried by creating different types of projects:
- Graphical application
- GTK+2 application
- GTK+3 application
- QT application
The same result: no icon!
Tried both XUbuntu with XFCE and LUbuntu with LXDE. No icon!
Tried on classic Ubuntu with Unity: icon appears in tray.
Tried on Kubuntu with KDE: icon appears in tray.
Also installed XUbuntu then removed XFCE and installed LXQT instead. Everything
works.
As I can understand the problem appears only when either LXDE or XFCE is useed
as desktop environment.
Best regards,
Abdul Zagirov!
