MATLAB: Ginput doesn’t accept keyboard entry as first input

Question

Hello all,

I have a figure in which I use ginput() to have coordinates. I ask the user to use left click, right click or keyboard's space in order to have coordinates of three specifics points. But ginput doesn't respond to any keyboard input till I click on the axes. After the first click it will accept all keyboard inputs.

My code:

    [clicX, clicY, clicButton] = ginput(1);
    while isempty(clicButton) ~= 1      % ENTER to quit
      switch clicButton
        case 1     % Left click
          ...
        case 2     % Right click
          ...
        case 32    % SPACE key
          ...
      end
      [clicX, clicY, clicButton] = ginput(1);
    end

I try to add figure(handle) before ginput() in order to Matlab to focus, but whithout any results.

Is someone have a solution ?

Thanks

Answer 1

dbtype ginput

At around line 87 does it have a comment that begins with g467403 ? If so then I suspect that section to be the difficulty, that possibly before the click the wrong figure is the first child.

Possibly what might work is

uistack(handle, 'top')
