Youimplement graphical user interfaces using uicontrols. When selected, mostuicontrol objects perform a predefined action. MATLAB supports numerousstyles of uicontrols, each suited for a different purpose:• Check boxes• Editable text• Frames• List boxes• Pop-up menus• Push buttons• Radio buttons• Sliders• Static text• Toggle buttonsCheck boxes generate an action when clicked on. These devices are useful whenproviding the user with a number of independent choices. To activate a checkbox, click the mouse button on the object. The state of the device is indicated onthe display.Editable text boxes are fields that enable users to enter or modify text values.Use editable text when you want text as input.On Microsoft Windows systems, if an editable text box has focus, clicking on themenu bar does not cause the editable text callback routine to execute. However,it does cause execution on UNIX systems. Therefore, after clicking on the menubar, the statementget(edit_handle,'String')does not return the current contents of the edit box on Microsoft Windowssystems because MATLAB must execute the callback routine to update the2-534
