MATLAB: Gui

guiMATLAB

hi im new for gui. Anybody can tel me what is meant by create function , delete function and button down function, when we can use it in gui?

Best Answer

The question is very basic. I recommend to read the Getting Started chapter in the documentation.

The CreateFcn is called, when a figure is created.
The DeleteFcn is called, when the figure is deleted.
The ButtonDownFcn is called, when the mouse is click over the figure area and no other GUI-element (e.g. a button) catchs the event.

To find corresponding locations in the documentation:

docsearch DeleteFcn

MATLAB: How to add a graphics object callback subfunction to a GUI MATLAB program using GUIDE in MATLAB

Graphics objects can have additional callback routines like ButtonDownFcn, CreateFcn, and DeleteFcn, which are executed with the appropriate user action.

Figures can also have the following callbacks:

CloseRequestFcn

KeyPressFcn

ResizeFcn

WindowButtonDownFcn

WindowButtonMotionFcn

WindowButtonUpFcn

To add a callback subfunction to the MATLAB program:

1. Click the right mouse button while the object is selected to display the Layout Editor context menu

2. Select View Callbacks

3. Select the desired callback from the context menu

GUIDE then adds the subfunction stub to the MATLAB program file for the GUI.

MATLAB: WindowButtonDownFcn conflicting with ButtonDownFcn

You can insert an axes object spanning this whole figure as a background and use its ButtonDownFcn:

BGcolor = get(0, 'DefaultFigureColor');
BGaxes = axes('Units', 'normalized', 'Position', [0,0,1,1], ...
              'XTicks, [], 'YTicks', [], ...
              'Color', BGcolor, 'XColor', BGcolor, 'YColor', BGcolor, ...
              'ButtonDownFcn', 'disp(''Background'')');
DataAxes = axes('ButtonDownFcn', 'disp(''Data'')';
