Several questions to disturb, please !
(1). In 'guitest.cxx', I add:
const TGPicture *pic ;
...........................
pic = fClient->GetPicture("mb_stop_s.xpm");
................................
fPictButton = new TGPictureButton(f1, pic, 100);
and in ' ProcessEvent', I add the following :
case kCM_BUTTON:
................
case 100:
fClient->FreePicture(pic);
pic = fClient->GetPicture("home_t.xpm");
fPictButton->DoRedraw();
break;
But the compilation will give the errors messages like:
>>>> CC: error: cannot open message catalog: CC.cat
>>>> CC: "oo.c", line 935: error: unknown message (1299)
where line 935 is "fPictButton->DoRedraw();"
(2). Is there any implementation in ROOT that make some warning sound like
'beep' function in UNIX ? It would be nice if the sound can continues
till you switch it off.
(3). Is the size of a TGPictureButton determined by that of the picture
inside ? I did not find any implemtation that can resize the button.
Sincerely,
xie
