## 6: Using layouts inside GUIDE GUIs

Whilst the layouts in this toolbox do not integrate into the MATLAB Graphical User Interface Design Environment (`GUIDE`), it is possible to insert layouts into a GUIDE-built GUI as follows:

#### Create the GUIDE GUI

Create you GUIDE application as usual, placing a panel where you want to insert the layout. You can turn the panel border and title off if you do not want them.

#### Insert the layout

Edit the "OpeningFcn" in the GUIDE-created code and insert your layout into the panel, making it fill the space. In the example below four boxpanels are inserted into a grid, which itself is placed inside `uipanel1`:

    % --- Executes just before guideApp is made visible.
    function guideApp_OpeningFcn(hObject, eventdata, handles, varargin)

    % Choose default command line output for guideApp
    handles.output = hObject;

    % Update handles structure
    guidata(hObject, handles);

    % Put a layout in the panel
    g = uiextras.GridFlex( 'Parent', handles.uipanel1, ...
        'Units', 'Normalized', 'Position', [0 0 1 1], ...
        'Spacing', 5 );
    uiextras.BoxPanel( 'Parent', g, 'Title', 'Panel 1' );
    uiextras.BoxPanel( 'Parent', g, 'Title', 'Panel 2' );
    uiextras.BoxPanel( 'Parent', g, 'Title', 'Panel 3' );
    uiextras.BoxPanel( 'Parent', g, 'Title', 'Panel 4' );
    g.RowSizes = [-1 -1];
