416 Chapter 4 Programming in Matlab hLineWidthText=uicontrol(... ’Style’,’text’,... ’Parent’,hPanel,... ’Position’, [10 180 180 20],... ’String’, ’Enter Desired LineWidth: (1-10)’,... ’HorizontalAlignment’,’Left’,... ’BackgroundColor’, panel_color); Next, to initialize the edit box for our GUI, enter the following lines just below the last uicontrol, the static text control with handle hLineWidthText. hLineWidthEditbox=uicontrol(... ’Style’,’edit’,... ’Parent’,hPanel,... ’Units’,’Pixels’,... ’Position’, [10 150 180 25],... ’String’,’1’,... ’BackgroundColor’, buttongroup_color,... ’Callback’, @LineWidthEditbox_callback); Some comments are in order. • Note that the ‘Style’ is ‘edit’, so this uicontrol is a dynamic edit box, one where both user and program can modify the text inside. • The parent is the uipanel, so the position of the edit box will be measured from the lower left-hand corner of the panel with handle hPanel. • We intialize ‘String’ to ‘1’. This will be the intial value that appears in the edit box. It represents a line width of 1 point (1 pt). • We assign the function handle @LineWidthEditbox_callback to the ‘Callback’ property. At this point, if you attempt to modify the text in the dit box, you will receive an error as the callback function LineWidthEditbox_callback is not yet written. Let’s take care of that immediately and write the callback. As usual, the obligatory arguments hObject and eventdata are used.
