Hi,

i have a little problem.
in my static function (static void Project::on_call()).
this static function is active when have someone call to me.
(i make Softphone)

when have someone call to me, i want the popup window to show who call to me and show "Accept" or "Reject" like X-Lite or Skype.

So..

static void Project::on_call(){

//CODES

if(PromptOKCancel("Accept?")){
    /* answer incoming calls with 200/OK */
    		pjsua_call_answer(call_id, 200, NULL, NULL);
    }
}

it build complete, But when i use program when someone call to me, the programe is crash. and it say

(<unknown>:7856): Gdk-CRITICAL **: gdk_pixmap_foreign_new_for_screen: assertion `GDK_IS_SCREEN (screen)' failed

(<unknown>:7856): Gdk-CRITICAL **: gdk_drawable_set_colormap: assertion `GDK_IS_DRAWABLE (drawable)' failed

(<unknown>:7856): Gdk-CRITICAL **: gdk_drawable_get_depth: assertion `GDK_IS_DRAWABLE (drawable)' failed

(<unknown>:7856): Gtk-CRITICAL **: gtk_paint_box: assertion `style->depth == gdk_drawable_get_depth (window)' failed

(<unknown>:7856): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
Segmentation fault (core dumped)

and Program is crash.

sometime is

Xlib: unexpected async reply (sequence 0x20a7)!

GUI is crash but function is working

so i use Layout to static function

in Project.h

class Project : public WithTopLayout<TopWindow>{
	WithAccountLayout<TopWindow> account;
	WithRingLayout<TopWindow> ringer;	
        ...
        ...

static void Project::on_call(){

//CODES

ringer.Execute();

but build incomplete, it say

...
/home/watchara/upp/MyApps/Project/Project.h:19: error: invalid use of member �Project::ringer� in static member function
/home/watchara/upp/MyApps/Project/Project.cpp:62: error: from this location
...

I am sorry, the description is far confusing. Do you think you could create a simple testcase to demonstrate the problem?

Well, it should not crash in the first place.

If it does, there are two possible explanations:

- something else is wrong with your code - hard to say what

- there is a bug in U++

I guess that by creating a simple testcase, you can investigate both alternatives. If second one proves true, posting a testcase here will significantly speedup the fix.
