I am having 2 visual problems in my Lazarus IDE built with GTK2 on Linux Mint 64-bit.

1. Menus don't show icons. Main menu and popup menus have the same problems.

2. The hint on an editor tab showing the whole file name is cut in half. The end part of the text is covered with black. There was a bug like this some years ago.

With QT interface it works well.
Does anybody else see this problem?

Juha

gtk apps normally do not show icons in menus.

Change Application.ShowMenuGlyphs to sbgAlways

Mattias

In gtk2 theme settings that could be enabled too (don't know exactly what property it should be).

zeljko

in the program TWEAK has an option to activate the menu images and buttons of the programs implemented in the system.

Hi,
had the same problem with missing icons with GTK some time ago, I think I resolved the issue with

update-mime-database ~/.local/share/mime

but I can't remember exactly...

d.l.i.w

I have KDE here. I found a setting for GTK applications in KDE control center but unfortunately it made no difference.
I am also getting hundreds of messages like this:

(lazarus:9608): Gdk-WARNING **: Attempt to draw a drawable with depth 24 to a drawable with depth 32

I guess it is related to the problem.

update-mime-database ~/.local/share/mime

The syntax was right but it made no difference either.

Anyway this is not a big problem. I mostly use QT bindings myself and it works well.
It is enough to know that the problem is in my machine configuration and not a bug in GTK2 bindings.

Juha

I've got a main menu with some LEDs on it as icons, x86 Debian 6 "Squeeze" KDE, LCL 1.1 R39139. Don't think I had to do anything outrageous to get it working on GTK2, but (from memory) it doesn't work on Qt.

Hi all

I have the same problem as Juha with the menu icons having dissapeared. This is on 64 bit Mageia Linux with the latest lazarus and fpc from svn. Also I have noticed that in the object inspector if I try to change the colour of a component, the list of colours is corrupted so that the boxes with the colours all look the same, almost as though they were drawn with ink and someone has spilled water on it.

Regards

Tim

Do you use KDE or Gnome?
Do you run the gtk2 or the qt version of Lazarus?
When has it worked?

Mattias

My Lazarus IDE menu has icons, and the OI colour selector is fine.

Ubuntu 11.04
Lazarus 1.1 r41161 FPC 2.6.3 i386-linux-gtk 2
and
Lazarus 1.1 r41161 FPC 2.7.1 i386-linux-gtk 2

My lazarus has no icons in menu, GTK widgetset, KDE, x86_64 ubuntu. Revision 40173.

Michael.

Thanks.

For those who think that their gtk settings is treated wrong by the LCL and want to debug it:

The code is in
lcl/interfaces/gtk2/gtk2themes.pas

function TGtk2ThemeServices.GetOption
and
procedure MenuImagesChange

I'm not the original poster but I'm using mageia 2 64 bits too and I just noticed the same problem (but with lazarus 1.0.8), however, the colours in the colour selection combo-box are not washed up, they're just transparent (I can see through the text that lies below). I'm using kde and the gtk2 version of Lazarus.
Kde applications have icons in the menus, as do other gtk2 applications (like, e.g. thunderbird)

gtk has a boolean flag 'gtk-menu-images' to control it. By default it is false.

Mattias

That's my code. It checks the next style options:

1) For button images. It creates a button with default options and looks for 'gtk-button-images' option.

2) For menu images. It create a menu item with default options and looks for 'gtk-menu-images' option.

It also listens for those option changes.

I remember I tested this rather much on some ubuntu.

Btw, if you want you can change this default behavior by:

a) changing your theme settings
b) changing in IDE options (if you want this for IDE) / changing in TApplicationProperties object.

Best regards,
Paul Ishenin

I also use a KDE desktop and Lazarus Gtk2.

If using the default Gtk theme oxygen-gtk there is no icon. By setting another theme (Clearlooks, qtcurve) all the menu have an icon.

Just to be sure breakpoints are working, I also put one in InitThemes and it stops there as it should.

Try another theme or use a tool like dconf to change 'menus-have-icons', which is internally 'gtk-menu-images'.

however, the colours in the colour selection combo-box are not washed up, they're just transparent (I can see through the text that lies below).

This is not related.

I'm using kde and the gtk2 version of Lazarus. Kde applications have icons in the menus, as do other gtk2 applications (like, e.g. thunderbird)

Maybe Mageia did something special for thunderbird.

From Patrick Chevalley : If using the default Gtk theme oxygen-gtk there is no icon. By setting another theme (Clearlooks, qtcurve) all the menu have an icon.

I can confirm that. All the problem are gone after switching to "Raleigh" Gtk2 theme (I don't have other choices there. Clearlooks etc. are KDE themes).

These output lines were clearly related to the problem, they are also gone now :

(lazarus:10785): Gdk-WARNING **: Attempt to draw a drawable with depth 24 to a drawable with depth 32

The other problems, namely the dim Color dropdown list and the cut-off file name in editor tab's hint, are also cured by changing the Gtk2 theme in KDE.

I guess this happens only with KDE 4.10.x. I updated my Mint 14 for KDE 4.10 and the problem may have started then. It is not dependent on Lazarus revision.
Can others confirm to have KDE 4.10?

Juha

[...] I guess this happens only with KDE 4.10.x.

I can not get menu icons under Ubuntu, even if I want, which I don't.

Menu icons are good. Why would somebody not want them?

Anyway, it seems other GTK apps like Gimp respect a setting : "Show icons in GTK menus"
in KDE control center. Lazarus does not. Something is different.

Does that mean we have to call

gtk_image_menu_item_set_always_show_image(menu_item,1);

?

They are too small to recognize what they mean.

Ok. Then check how DrawMenuItemIcon works and debug it in gtk2proc.inc

I am using the gtk2 version. I have only recently changed to a 64 bit OS. Previously I was using Mandriva 2012 32bit on the same hardware and everything worked fine. I am using xfce.

Tim

Based on Tim's and Luca's posts KDE is not related to the problem. However 64-bit OS is related. Can others confirm it?

Anyone else saw these lines in stderr :

(lazarus:10785): Gdk-WARNING **: Attempt to draw a drawable with depth 24 to a drawable with depth 32

They show in the same console you started Lazarus from.

Juha

That routine is avaliable from gtk-2.16, and we are still supporting minimum = 2.8.

As Mattias said, they are too small, and often the action based on the icon (if you can make out what the picture is) isn't well represented. And then the most obvious one... the menu item already has clear readable text, telling the user exactly what the menu item does. So why do you need two things (icon and text) to tell a user what a menu item does?

Toolbars are obviously a different matter, because often they don't have any text next to them - so the icon is all you have to go on. This is never the case with menus though - you always have the text part.

I can confirm that I also get this message

I have the same problem as Juha with the menu icons having dissapeared.

I'm running JWM (Joe's Window Manager) under 64-bit FreeBSD. Menu icons are (unfortunately) still visible in all Gnome and KDE applications on my system.

Switching to a Gnome 2 desktop environment, Lazarus (compiled with GTK2 interface) correctly adheres to the Gnome gconf setting - just like all the other GTK2 apps. So I can't reproduce the issue here.

What happens if you set Tools / Options / Desktop / Show glyphs for menus to "always" and restart the IDE?

I'm under 64-bit FreeBSD, and Lazarus (trunk) compiled with LCL-GTK2. I do not see any such output when I start Lazarus IDE.

You understood me wrong. :) Lazarus IDE displays the menu icons correctly, when you compare it to other GTK applications. If I disable/enable the showing of glyphs in the IDE, the IDE acts as it should.

The issue on my system is that I can't disable button and menu icons for _all_ GTK2 apps under JWM - probably because DBUS, or GConf or whatever GTK/Gnome uses isn't loaded in just a X11 Window Manager environment (no desktop environment is loaded). This has nothing to do with Lazarus though.

When I do run Gnome 2 (whole desktop environment), Lazarus IDE does work as it should. So like you, I can't reproduce the issue the original poster mentioned.
