如何在启动时最大化MATLAB GUI图形/窗口？

Question

I am currently evaluating GUIs in MATLAB and was wondering how to maximize a GUI window on startup, without the need for user interaction. The function I am using is stated hereafter and works fine if called on a button press, but calling it in the figure's OpeningFcn won't help.

Any help on some startup section to place the function call, which is executed after the GUI window has been drawn? I searched for solutions related to startup code in MATLAB GUIs, but there were no results to date. Thanks in advance for your efforts.

Since many people seem to be interested in this and there is still no public solution, I will describe my approach:

1. In the YourGUIName_OpeningFcn(hObject, eventdata, handles, varargin) function, append the following lines:

    % Initialize a timer, which executes its callback once after one second timer1 = timer('Period', 1, 'TasksToExecute', 1, ... 'ExecutionMode', 'fixedRate', ... 'StartDelay', 1); % Set the callback function and declare GUI handle as parameter timer1.TimerFcn = {@timer1_Callback, findobj('name', 'YourGUIName')}; timer1.StopFcn = @timer1_StopFcn; start(timer1); 

2. Declare the timer1_Callback and timer1_StopFcn functions:

    %% timer1_Callback % --- Executes after each timer event of timer1. function timer1_Callback(obj, eventdata, handle) % Maximize the GUI window maximize(handle); %% timer1_StopFcn % --- Executes after timer stop event of timer1. function timer1_StopFcn(obj, eventdata) % Delete the timer object delete(obj); 

3. Declare the maximize function:

    function maximize(hFig) %MAXIMIZE: function which maximizes the figure withe the input handle % Through integrated Java functionality, the input figure gets maximized % depending on the current screen size. if nargin < 1 hFig = gcf; % default: current figure end drawnow % required to avoid Java errors jFig = get(handle(hFig), 'JavaFrame'); jFig.setMaximized(true); end
