Thread Subject: positioning of questdlg

Hi,

I use questdlg quite often and it always appears in the
middle of the screen, where it covers the information which
is needed for the answer.
Is it somehow possible to set its position?

thanks for your help in advance

You will have to modify the questdlg according to your
required position

edit questdlg

and modify the position property inside the code.

i took a look and didn't see much promising stuff. as a
workaround, you could write your own gui that does the same
thing as questdlg but has options to send it parameters for
location. shouldn't take too long...

thank the both of you for the hint, it?s no big deal but
surprsing that this option is missing

"Error Dialog Box (errordlg) Position"

Though that posting referred to errordlg, the same applies to
questdlg.

I dont think thats possible Walter, because errordlg gives
the handle of the figure to the output, while questdlg
doesnot, moreover, questdlg has to wait for the user input.

For the O.P:
If you want to design something similar to questdlg real
quick you can refer to my submission on "A small gui
Example" posted here
http://www.mathworks.com/matlabcentral/fileexchange/loadFil
e.do?objectId=18212&objectType=file.
You can place movegui(gcf, 'northwest'), or you preferred
position in the opening_fcn in that example..

Good point, but I gave two solutions in that thread, and the
second one applies:

  The figure location for errordlg {and now questdlg} is given by
  the root property DefaultFigurePosition.

questdlg then potentially modifies it by calling
getnicedialoglocation to center the dialog in the upper third of
the screen.

Hello Walter
Could you please provide some suitable example.
I have not quite understood, how we could accomplish the
above by your method?

Tracing the code more carefully, I see that in fact the
DefaultFigurePosition values are obtained but then completely
ignored. The question dialog will be horizontally centered on the
figure (or on the screen if there is no current callback object),
and will be vertically set to start 1/3 of the way down the figure
(or screen).

Due to bugs in the code, the only way to affect the positioning
would be to change the root DefaultFigureUnits -- the
code uses absolute sizes for the question dialog box, but
uses DefaultFigureUnits as the units when it queries the size
of the figure or screen. The resulting mix could throw the
calculation off completely, positioning the question dialog in
strange places, I believe.

thank you both for the further discussion, setting a new
value for 'DefaultFigurePosition' has no effect, i just
changed questdlg

Hi,

It might be too late, but you can determine the question dialog box position on the screen by the Modified Function 'MFquestdlg':

Hope this helps.
