In DECwrite, DECdecision or Paint, you must have noticed that there
are some items in some pull-down memus are disable and its text color
is much lighter than other enabled item. This happens when you're in
some specific mode.
I would like to implement this feature in my user interface but I can't
find any example showing this feature. Could any tell me how to program
it in XUI? Any example available?

| 3256.1 | Set the sensitivity attribute of the push_button | TOWNS::RUFFIEUX | Fri Aug 24 1990 12:57 | 35 | |
If I am understanding you correctly, you would like to set the
sensitvity of a push_button in a pull-down menu.
step 1: Be sure to do a create in your UIL on the push_button.
Also, you can set the initial sensitivity here. ( By default
it is True, meaning you CAN use it )
object
button_pb : push_button {
arguments {
label_label = compound_string('Button');
sensitive = false;
};
callbacks {
create = procedure createCB(BUTTON_PB);
};
};
Step 2: Now, in you C code ( or whatever language you use ) when
you are ready to make the button accessible:
Arg al[1];
.
.
XtSetArg(al[0],DwtNsensitive,True);
XtSetValues(widgets[BUTTON_PB],al,1);
This will make the button sensitive.
Hope this helps...

> XtSetArg(al[0],DwtNsensitive,True); > XtSetValues(widgets[BUTTON_PB],al,1); Calling XtSetSensitive might be more efficient: XtSetSensitive(widgets[BUTTON_PB], True); | |||||

The other advantage of XtSetSensitive (over XtSetValues) is that it cascades into children. That way you can set a menu and its children insensitive with a single call. This can be especially important for affecting complex widgets which are made up of multiple children (ie: list box). In that case the XtSetValues call may not affect the children resulting in unexpected behavior. Dick | |||||
