Subject: focus lost after option menu selection
Full_Name: E. Weber
Version: 2.4.14
CVS_Date:
OS: red hat linux 8.0
X_Server: Xfree86, Exceed
Submission from: (NULL) (53.122.197.194)
The problem appears while using Motif (version 2.2.3) option menus under
FVWM2 with the Focus Follows Mouse option. (It doesn't appear with fvwm1
or with Click To Focus option).
Selecting option menu entries twice or more the option menu looses focus.
The related window is still the active window, but there isn't a focus in
the whole window.
Focus reappears as the mouse is moved out of the window and in again.
The problem seems to be caused by calling XmAddWMProtocolCallback for Atom
WM_TAKE_FOCUS.
Reproduction of the problem can be done with the following code:
#include <stdio.h>
#include <stdlib.h>
#include <Xm/Xm.h>
#include <Xm/PushB.h>
#include <Xm/RowColumn.h>
#include <Xm/RowColumn.h>
#include <Xm/Protocols.h>
void emptyCB(Widget widget, XtPointer clientDaten, XtPointer aufrufDaten)
{}
int main(int argc, char **argv)
{
XtAppContext kontext;
Widget applShell;
Widget box, option_menu, menu, button1, button2;
int ac=0;
Arg al[64];
applShell= XtAppInitialize( &kontext, "focustest", (XrmOptionDescRec*)
NULL, 0, &argc, argv, (String*) NULL, (Arg*) NULL, 0);
box= XtCreateManagedWidget("box", xmRowColumnWidgetClass, applShell,
(Arg*)NULL, 0);
option_menu = XmCreateOptionMenu ( box, (char *) "option_menu", al, ac
);
menu = XmCreatePulldownMenu ( option_menu, (char *) "menu", al, ac );
button1 = XtCreateManagedWidget("button1", xmPushButtonWidgetClass,
menu,
(Arg*)NULL, 0);
button2 = XtCreateManagedWidget("button2", xmPushButtonWidgetClass,
menu,
(Arg*)NULL, 0);
XtSetArg(al[ac], XmNsubMenuId, menu); ac++;
XtSetValues(option_menu, al, ac);
XtManageChild(option_menu);
Atom wm_take_focus = XInternAtom( XtDisplay( applShell
),"WM_TAKE_FOCUS",
True );
XmAddWMProtocolCallback( applShell, wm_take_focus, emptyCB,
(XtPointer) NULL );
XtRealizeWidget(applShell);
XtAppMainLoop (kontext);
}
