Hi,
I try the first time to use a tray-icon. I want that as soon as the window gets minimized (ICONIFIED) it shall go to the tray. If I left click the tray-icon the window should come back again to the screen. But this doesn't work as I want it.

First my code:

Code: (C)

#include <gtk/gtk.h>

static void trayIconActivated(GObject *trayIcon, gpointer data);
static gboolean window_state_event (GtkWidget *widget, GdkEventWindowState *event, gpointer user_data);

int main(int argc, char *argv[])
{
gtk_init (&argc, &argv);

GtkWidget *window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
gtk_widget_set_size_request (window, 200, 200);

GtkStatusIcon *trayIcon = gtk_status_icon_new_from_icon_name(GTK_STOCK_MEDIA_STOP);
gtk_status_icon_set_tooltip (trayIcon, "My trayicon test");
gtk_status_icon_set_visible(trayIcon, FALSE);
g_signal_connect(GTK_STATUS_ICON (trayIcon), "activate", GTK_SIGNAL_FUNC (trayIconActivated), window);

g_signal_connect (G_OBJECT (window), "window-state-event", G_CALLBACK (window_state_event), trayIcon);

gtk_widget_show(window);
gtk_main ();
return 0;
}

static void trayIconActivated(GObject *trayIcon, gpointer window)
{
gtk_widget_show(GTK_WIDGET(window));
gtk_window_deiconify(GTK_WINDOW(window));
}

static gboolean window_state_event (GtkWidget *widget, GdkEventWindowState *event, gpointer trayIcon)
{
if(event->changed_mask == GDK_WINDOW_STATE_ICONIFIED && (event->new_window_state == GDK_WINDOW_STATE_ICONIFIED || event->new_window_state == (GDK_WINDOW_STATE_ICONIFIED | GDK_WINDOW_STATE_MAXIMIZED)))
{
gtk_widget_hide (GTK_WIDGET(widget));
gtk_status_icon_set_visible(GTK_STATUS_ICON(trayIcon), TRUE);
}
else if(event->changed_mask == GDK_WINDOW_STATE_WITHDRAWN && (event->new_window_state == GDK_WINDOW_STATE_ICONIFIED || event->new_window_state == (GDK_WINDOW_STATE_ICONIFIED | GDK_WINDOW_STATE_MAXIMIZED)))
{
gtk_status_icon_set_visible(GTK_STATUS_ICON(trayIcon), FALSE);
}
return TRUE;
}

You can compile the example with: gcc test.c -o test `pkg-config --cflags --libs gtk+-2.0`

So hiding is no problem. If I minimize the window it gets ICONIFIED and window_state_event reacts by hiding the window and showing the tray-icon.

But If I now left-click on the tray icon the window seems to appear for a milli-second in the applicationbar but minimized and so window_state_event directly makes it disappear again.

My suspision is:

Code: (C)
1 2 3 4 5 6 7	static void trayIconActivated(GObject *trayIcon, gpointer window) { gtk_widget_show(GTK_WIDGET(window)); gtk_window_deiconify(GTK_WINDOW(window)); }

gtk_widget_show just makes the window show ICONIFIED and even before I can change this with gtk_window_deiconify the window_state_event makes the window disappear again.

Any idea how to solve this problem or where the bug in my code is?

well, on windows it works okay, and works perfectly if you change:

Code: (C)
1 2 3 4 5	static void trayIconActivated(GObject *trayIcon, gpointer window) { gtk_widget_show(GTK_WIDGET(window)); gtk_window_deiconify(GTK_WINDOW(window)); }

to

Code: (C)
1 2 3 4 5	static void trayIconActivated(GObject *trayIcon, gpointer window) { gtk_window_deiconify(GTK_WINDOW(window)); gtk_widget_show(GTK_WIDGET(window)); }

does changing this make it work for you?

No I also already tried it but I have the exact same behavior like before :(

It seems I can't deiconify a withdrawn window or widget.show changes this again.

OS: linux

But:

Code: (C)
1 2 3 4 5 6 7 8	static void trayIconActivated(GObject *trayIcon, gpointer window) { gtk_window_deiconify(GTK_WINDOW(window)); gtk_widget_show(window); gtk_window_deiconify(GTK_WINDOW(window)); }

makes it work 50% , so every second time I wanna show the window again it works and the other time it is just as I described above.

Well, using my version (with gtk_widget_show second) on kubuntu 8.04 it works fine.
which distribution do you use?

a small question from my side.
