Generalised question dialog (questdlg)

A question dialog (questdlg) alternative

Description

Create and open a push button dialog box, which is a generalized version of a question dialog box (called by questdlg). User can enter any number of input options (buttons)for one to choose from, as opposed to questdlg, where only 2 or 3 options are supported. User can also set the buttons ordering (columns, rows). Dialog will attempt to set parameters to optimally present button text.

• Required Products: MATLAB
• MATLAB release: MATLAB 7.12 (R2011a)

Dear Nikolay S. and Dan K.,

A very happy new year to you two also. After Dan's modification I am having no problem running this .m file. It has been hugely helpful, so my thanks to you both.

Louis

Good evening and Happy New Year Dan K and Louis Vallance. Thank you for your comments. it seems you both are right, while I was wrong. indeed this failed to work. Dan K proposal fixes the problem. My compliments

[Louis Vallance]

Hi again.

I tested the example provided in your code and iSel is 3 (the default selection) regardless of which button is pressed. Is there a fix for this, cause otherwise the program doesn't work.

Cheers

Hi Nikolay,

With the old questdlg I could just say variable=questdlg(inputs) and the button I pressed would be assigned to variable. With this function it doesn't seem to be working.

Hi Nikolay,

Thanks for responding. I am running R2012a(7.14.0.739). What example are you using?

For testing, I called both the FEX code, and the modified code with the following syntax:

>> selectedIndex=bttnChoiseDialog({'str1', 'str2', 'Cancel'}, 'Selection', 'Cancel','Which str?')

With the original code, selectedIndex is set to 3 for pushes on either str1 or str2 (the default button, "cancel" is at index #3 and has it's "value" property set to true, which is then found in the function line: "choise=find( cell2mat( get(buttnHndl, 'Value') ) ); "). The modified code returns 1 for str1 and 2 for str2 (using the handle of the object that executed the callback, it does not have to find a true or false value).

Good evening Dan. Thank you for your comment. As far as I can see you've changed the callback function, replacing 'uiresume(gcbf)' with your my_bttnCallBack service function.
I've tried your code with my exmaple, but it resulted in an error:
"Error in bttnChoiseDialog>my_bttnCallBack (line 201)
choise=find(strcmp(dlgOptions, get(hObject,'String')));

Error using waitfor
Error while evaluating uicontrol Callback"

My original code seems to work fine for the given example. i'm using Matlab 2011b. What version do you run?
Best regards.

The end of this function was not working as I was using it, so I changed this:

for iBttn=1:nButtons
[iRow, iCol]=ind2sub([bttnRows, bttnCols],iBttn);
currBttnHeigth=figH-titleSps-iRow*interBttnStpH;
currBttnLeft=(iCol-1)*interBttnStpW+spaceW+(interBttnStpW-bttnW-spaceW)/2;

buttnHndl(iBttn) = uicontrol( buttonGroup, 'Style', 'pushbutton',...
'FontUnits', 'normalized', 'Units', 'characters', 'FontSize', bttnFontSize,...
'String', dlgOptions{iBttn}, 'Callback', 'uiresume(gcbf)',...
'Position', [currBttnLeft , currBttnHeigth, bttnW, bttnH] );
end
set(buttnHndl(iDefOption), 'Value', 1); % set default option
set(cat(1, buttnHndl, titleH, buttonGroup),'Units', 'normalized')

uiwait(menuFigH); % wait untill user makes his choise, or closes figure

choise=find( cell2mat( get(buttnHndl, 'Value') ) );
delete(menuFigH);

to

for iBttn=1:nButtons
[iRow, iCol]=ind2sub([bttnRows, bttnCols],iBttn);
currBttnHeigth=figH-titleSps-iRow*interBttnStpH;
currBttnLeft=(iCol-1)*interBttnStpW+spaceW+(interBttnStpW-bttnW-spaceW)/2;
buttnHndl(iBttn) = uicontrol( buttonGroup, 'Style', 'pushbutton',...
'FontUnits', 'normalized', 'Units', 'characters', 'FontSize', bttnFontSize,...
'String', dlgOptions{iBttn}, 'Callback', @my_bttnCallBack,...
'Position', [currBttnLeft , currBttnHeigth, bttnW, bttnH]);
end
set(buttnHndl(iDefOption), 'Value', 1); % set default option
set(cat(1, buttnHndl, titleH, buttonGroup),'Units', 'normalized')

uiwait(menuFigH); % wait untill user makes his choise, or closes figure

delete(menuFigH);

function my_bttnCallBack(hObject, ~)
choise=find(strcmp(dlgOptions,get(hObject,'String')));
uiresume(gcbf)
end

end
