MATLAB: GUI: Change keyboard focus to listbox

focusguikeyboardlistbox

I've got a workflow related GUI question.

Situation: A GUI with 3 buttons and a listbox. Buttons populate listbox with various content.

What i want to do: When i press the buttons, I want focus to shift to the listbox automatically. This so that the user may easily navigate the listbox using the arrow-keys and use ctrl+a if needed, without having to press tab first.

I tried changing the main GUI property 'CurrentObject' to the listbox handle, but this had no effect. Also, changing the listbox handle property 'Selected' to 'on' had no effect.

Does anyone have a solution?

MATLAB: How to make a push button respond to clicking with the right mouse button

There are two properties which can be used in conjunction to accomplish this.

One is the button's 'ButtonDownFcn' callback function. This callback function executes when pressing a mouse button on or near a UICONTROL object -- including when pressing the right mouse button.

The other property is the figure's 'SelectionType' property. This property indicates which kind of click was registered in the figure window -- including clicks on controls within the figure.

Putting these two together, you can define a 'ButtonDownFcn' callback for a push button which checks the figure's 'SelectionType' property to detect a right-click. An example is shown below. (In that example, the ANCESTOR function is used to get the figure's handle. If this is being done in a GUIDE-created GUI, this is unnecessary as the 'handles' structure already provides access to the figure's handle.)

function test
      uicontrol('Style', 'pushbutton', ...
                'ButtonDownFcn', @myCallback);
end
function myCallback(src, evt)
      figHandle = ancestor(src, 'figure');
      clickType = get(figHandle, 'SelectionType');
      if strcmp(clickType, 'alt')
          disp('right click action goes here!');
      end
end

MATLAB: Load listbox content with main form

Simon - if you have created your GUI using GUIDE, then put this fill_listbox function in the _OpeningFcn of your GUI. Else, if you are creating your GUI programmatically, then you can call this function soon after you have created the controls and just before you show the GUI.
