GuiControl is the virtual base class where common functionality is defined for all the controls and views that we use to create the user interfaces (Figure 1).

  • Use guicontrol_button and others to do dynamic casting between types.
  • Use guicontrol to convert derived types.
  • Use guicontrol_enabled to enable or disable a control.
  • Use guicontrol_visible to show or hide a control.
  • Scheme with the base class and derivatives of GuiControl.
    Figure 1: Controls and views.
  • Label. Small blocks of descriptive text.
  • Button. Push buttons, check boxes or radio.
  • PopUp. Button with drop-down list.
  • Edit. Text edit box.
  • Combo. Edit box with drop-down list.
  • ListBox. List box.
  • UpDown. Increment and decrement buttons.
  • Slider. Sliding bar.
  • Progress. Progress bar.
  • View. Generic view where you can freely draw.
  • TextView. View to show and edit texts in multiple formats.
  • ImageView. View to display images.
  • TableView. Table view to display information in rows and columns.
  • SplitView. View divided into two resizable parts.
