[originally post to webkitgtk dev list]
I'm porting a webkitgtk app from Fedora 16 to Fedora 20 and I have hit a
problem with the X11 event mask not allowing mouse or keyboard input.
The app has been ported to gtk3 but I'm still using the webkit1 API.
The RPM is: webkitgtk3-2.2.5-1.fc20.x86_64.
In this application there are no scroll bars and a controlling process
can set the size position and offset of the window that is drawn.
The Fedora 16 version of the code works as expected.
This is the key code I use to create the browser window:
m_widget_toplevel = gtk_window_new( GTK_WINDOW_TOPLEVEL );
m_window_toplevel = GTK_WINDOW( m_widget_toplevel );
m_widget_fixed = gtk_fixed_new();
m_fixed = GTK_FIXED( m_widget_fixed );
m_widget_webview = webkit_web_view_new();
m_webview = WEBKIT_WEB_VIEW( m_widget_webview );
WebKitWebSettings *settings = webkit_web_view_get_settings( m_webview );
g_object_set( G_OBJECT( settings ), "enable-file-access-from-file-uris",
TRUE, NULL
);
g_object_set( G_OBJECT( settings ),
"enable-universal-access-from-file-uris", TRUE,
NULL );
connectToSignals();
webkit_web_view_set_full_content_zoom( m_webview, TRUE );
gtk_fixed_put( m_fixed, m_widget_webview, 0, 0 );
gtk_window_set_title( m_window_toplevel, m_browser_name.c_str() );
// If we don't set the window to a size request of 1x1, it will
// default to the size of the largest child. GTK autolayout will
// then expand the window to the larger of the window size request
// or the size we set.
//
// We avoid problems elsewhere by using a GtkFixed to stop
// WebKit's size request bubbling up to the window.
gtk_widget_set_size_request( m_widget_toplevel, 1, 1 );
_setCanvasSize( *m_properties_active );
_setCanvasPosition( *m_properties_active );
_setWindowSize( *m_properties_active );
_setWindowPosition( *m_properties_active );
gtk_container_add( GTK_CONTAINER( m_widget_toplevel ), m_widget_fixed );
gtk_widget_grab_focus( m_widget_webview );
gtk_widget_show_all( m_widget_toplevel );
I added some debug to find the addresses of the key objects
and using gdb found the XID used by the GdkWindow.
Info: m_widget_toplevel is 0x6d8330 window is 0x6d8330 GdkWindow is 0x6b8280
XID = 0xc00003
Info: m_widget_fixed is 0x6c8210 window is 0x6c8210 GdkWindow is 0x6b8280
Info: m_widget_webview is 0x69e370 window is 0x69e370 GdkWindow is 0x6b84e0
Using xwininfo I can check the state of the X window that is created.
# xwininfo -tree -root
xwininfo: Window id: 0xa4 (the root window) (has no name)
Root window id: 0xa4 (the root window) (has no name)
Parent window id: 0x0 (none)
8 children:
0xa00002 "player_text_T6": () 2000x2000+2000+2000 +2000+2000
0xc00003 "player_html-o.H4": ("player_html" "Player_html") 1267x713+41+32
+41+32
1 child:
0xc00004 (has no name): () 1x1+-1+-1 +40+31
0x600002 "player_image_I3": () 1360x768+0+0 +0+0
0xc0000c (has no name): () 1x1+-1+-1 +-1+-1
0xc00001 "player_html": ("player_html" "Player_html") 10x10+10+10 +10+10

0x800002 "player_text_hiddenT6": () 1x1+2000+2000 +2000+2000
0x400001 "ntbglcomp": () 1x1+0+0 +0+0
0x200001 "screen_manager_hidden": () 1x1+2000+2000 +2000+2000
# xwininfo -events -id 0xc00003
xwininfo: Window id: 0xc00003 "player_html-o.H4"
Someone wants these events:
Exposure
VisibilityChange
StructureNotify
SubstructureNotify
PropertyChange
Do not propagate these events:
Override redirection?: No
The problem is that the m_widget_webview has a GdkWindows but does not
have a X window. The only X windows is realised for the m_widget_toplevel
and shared with m_widget_fixed.
What have I missed that makes GTK create the X window for m_widget_webview?
