Re^2: Tk multiple monitor problem

Yes, from what I gather, the problem with Show is that the check to make sure that it places popups in viewable area fails because the test doesn't realize that there is a left monitor. This is somewhat odd considering that you can use the geometry command to put the main window there.

Indeed, I have come up with a work around. It's tacky, but it works. Rather than fight Show's limitation, I use it as is, letting it place the popup incorrectly. Then I use a geometry command to move the popup to where it should be. Since your code stops running after the Show, I came up with the following way to accomplish this. Immediately prior to the Show I added the following.

$mw->after(2, \&Popup_Position_Fix, $popup, $popover);

The Popup_Position_Fix routine does some calculating then executes a geometry command on the popup. As I said, tacky, but it works. :)

As long as it works, tacky is beautiful :) but grepping through the source, -popover should have worked, go figure Tk/DialogBox.pm Read more... (1039 Bytes) Tk/Wm.pm Read more... (1471 Bytes)	[reply] [d/l] [select]

I did look at DialogBox.pm and a few others. This is why I feld that probably the Show routine was at fault. I did not know where to find Popup till your message, however. In Wm.pm I now see it. Indeed, this part of it would appear to cause the problem. `# adjust to not cross screen borders if ($X < 0) { $X = 0 }` [download] Unfortunately, when I change this line my code runs the same. So I'm mystified. Also in Wm.pm I noted the Post routine. It contains this. `$w->geometry("+$X+$Y"); # $w->MoveToplevelWindow($X,$Y);` [download] I'm guessing that the commented out MoveToplevelWindow call was replaced by the one to geometry (which works OK on multiple monitors). Thanks for the leads, however. :)	[reply] [d/l] [select]
