Re: [Oorexx-users] Dialog does not open with correct size.

[Oliver S. <oli...@si...>]

I tried your suggestions, but none worked (always assuming I changed things
properly).
 
(1) I tried making more room for the menu, but that didn't work.
 
(2) I tried connecting the size event  at the end of initDialog instead of
in the init method, but that didn't work.
 
(3) I tried self~execute('HIDE') then both self~show() and
self~show('SHOWTOP') at end of initDialog method, but that didn't work
either. In both cases, the dialog blinked into sight then disappeared again.
It wasn't minimized, and I had to kill the command prompt to end it. 
 
Any thoughts?
 
Many thanks,
Oliver
 
PS: This is not a major problem, just an annoying one. There's lots more I
can be getting on with.

Oliver,
 
A couple of thoughts, but I might have to see your code.
 
1.) I noticed that you don't seem to be taking into account the height of a
menu when you are using menus.  Dialogs weren't originally, (and really
still aren't,) intended to have menus.  So when you add a menu it has the
effect of pushing all the controls down the height of the menu.
 
When you are planning on adding a menu, whether you are using resource
editor or using UserDialog, you should make allowances for the menu.  In a
resource editor I usually make the bottom margin (the space between the
lower edge of the lowest control) 10 dialog units larger.  I.e., I normally
use a margin of 10.  When I'm going to add a menu I make the bottom margin
20.
 
This is likely sufficient to solve your problem.
 
2.)  When a dialog is first shown on the screen the operating system sends a
size message to it.  This event is what is sent when the user resizes the
dialog using the sizing border.  This will get passed on to the DlgAreaU
class and it will resize and move the controls as it normally does,  
 
It is likely that, since DlgAreaU does not know about the space taken up by
the menu, it resizes and moves the controls incorrectly.  I'm not sure if
this is happening, so it's one of those things I'd need to play with some
working code.  If this is the problem you could probably fix it by not
connecting the size event until you leave initDialog(),
 
3.) Similar to #2.  DlgAreaU does the initial resizing but for some reason
the dialog is not getting repainted immediately.  When you click the border,
it causes the OS to repaint the dialog.  Which is the effect you see of the
list-view changing size and the buttons becoming visible.  You might be able
to fix this by a.) giving the dialog the invisible style (i.e., do not give
it the visible style.)  b.) having it show after initDialog() is finished.
 
If #1 does not fix the problem, I would probably need to poke around a bit
with the dialog to determine the actual problem.  #2 and #3 are just
guesses, and how to fix them is just a guess also.  <grin>
 
Have you already checked in the code?  If so I'll just take a look at the
dialog in the user guide section of the samples.

In the User Guide's Exercise06, the Order Management dialog opens with the
two pushbuttons at the bottom of the dialog window only half visible. When I
click on the window border (no re-size - just a click) the ListView above
the buttons becomes less tall, and the button become fully visible.

I can't find a way of either getting the correct size of listview to appear,
or of emulating in code the click on the border to make the lisview shrink
to its proper starting size.

Btw, the dialog is re-sizeable and uses DlgArea and DlgAreaU.

Any thoughts?
