I am designing a GUI that requires toggles for axes equal, grid on/off, etc. These toggles work perfectly until the user double clicks on the axes, then they are overridden. Almost every other built-in function like this has some documentation available on how to control it, but I cannot find any documentation on this function.

If anybody could point me to a resource or tell me how to get into this function, it would be greatly appreciated! I do not necessarily want to stop the function, but rather control it to turn the toggles on/off or even read the status of the toggles and keep them consistent.

Any help is greatly appreciated! ~Josh

How do you control which axes are affected by the toggles?

The GUI is a single set of axes that the user selects which data to plot on x, y and z axes, then can change the axis mode (equal, tight, etc), grid on/off, etc. Since there is just one set of axes, it is easy to modify these properties. The problem is the double click function overrides them, and the users are getting annoyed to have to uncheck then recheck the toggles each time.

It works fine here. How are you doing things differently than this? I can double-click all I want on the axes and the toggles still work...

function [] = GUI_axes()
%  Problem with double-clicking on axes de-activating toggle callbacks?
S.fh = figure('units','pixels',...
              'position',[200 200 200 200],...

      % Callback for toggles.
          if isequal(varargin{1},S.tb(1))
              if get(S.tb(1),'value')
                  axis(S.ax,'square')
              else
                  axis(S.ax,'normal')
              end
          else

                  grid(S.ax,'on')

          end
      end
  end

I need the toolbars to be enabled so the user can pan, zoom, rotate, and use the data cursor. I modified your code to allow this and broke it. The grid toggle stays on, but the axes square does not.

Thanks for your help! Keep suggesting ideas please!

function [] = GUI_axes()

% Problem with double-clicking on axes de-activating toggle callbacks?

S.fh = figure('units','pixels',...

'position',[200 200 200 200],...

'menubar','figure',...

'toolbar','figure',...

'numbertitle','off',...

'name','GUI_axes',...

'resize','on');

S.ax = axes('units','pixels',...

'position',[30 70 160 120],...

'fontsize',8,...

'nextplot','replacechildren');

S.tb = uicontrol('style','toggle',...

'units','pixels',...

'position',[10 10 80 20],...

'call',{@tb_cb,S},...

'string','Square');

S.tb(2) = uicontrol('style','toggle',...

'units','pixels',...

'position',[100 10 80 20],...

'call',{@tb_cb,S},...

'string','Grid');

function [] = tb_cb(varargin)

% Callback for toggles.

if isequal(varargin{1},S.tb(1))

if get(S.tb(1),'value')

axis(S.ax,'square')

else

axis(S.ax,'normal')

end

else

if get(S.tb(2),'value')

grid(S.ax,'on')

else

grid(S.ax,'off')

end

This is getting me a little bit closer... now I know how to see the listeners that turn on when pan/zoom/rotate are on. Here is what I get when I make a simple plot of 50 random points:

>> Figure_Data = uigetmodemanager(fig);

>> Figure_Data.get

CurrentMode: [1x1 uitools.uimode]

Blocking: 0

>> Figure_Data.CurrentMode.get

WindowButtonDownFcn: {2x1 cell}

WindowButtonUpFcn: []

WindowButtonMotionFcn: {2x1 cell}

WindowKeyPressFcn: []

WindowKeyReleaseFcn: []

WindowScrollWheelFcn: {2x1 cell}

KeyReleaseFcn: []

WindowButtonMotionFcnInterrupt: 0

UIControlInterrupt: 0

KeyPressFcn: {2x1 cell}

ModeStartFcn: {2x1 cell}

ModeStopFcn: {2x1 cell}

ShowContextMenu: 1

Name: 'Exploration.Zoom'

IsOneShot: 0

UseContextMenu: 'on'

FigureHandle: [1x1 figure]

ButtonDownFilter: []

UIContextMenu: []

ModeStateData: [1x1 struct]

>> Figure_Data.CurrentMode.WindowButtonDownFcn

ans =

[function_handle]

[1x1 uitools.uimode]

ans =

ans =

@localStopZoom

[1x1 uitools.uimode]

>> Figure_Data.CurrentMode.FigureHandle

ans =

figure

>> Figure_Data.CurrentMode.ModeStateData

ans =

Constraint: 'none'

Direction: 'out'

Target: []

MaxViewAngle: 75

LineHandles: []

CurrentAxes: 170.0083

MousePoint: []

CameraViewAngle: []

CustomContextMenu: []

DoRightClick: 'off'

target: [1x1 figure]

I went into all of the options to show what they had one level down. Beyond this first level we are just chasing our tail, getting the exact same menus again and again.

So, anybody have an idea where to look for the double click function? I see the WindowButtonDownFcn, but this didn't have the double click inside.

Thanks for all your guys' suggestions!
