Now let's look at those properties, methods and events that are most common for all window objects encapsulated in the TControl object type. Since there are too many of these properties common to all types of "controls", I will try to divide them into groups and somehow classify them by purpose and scope:

 

•Window handle

•Parent and Child controls

•Availability and visibility

•Position and dimensions

•Painting

•Window text and font for the window

•Window color and window frame

•Messages (all window objects)

•Dispatching messages in KOL

•Keyboard and tabs between controls

•Mouse and mouse cursor

•Menu and Help

•Form and applet properties, methods, and events

oAppearance (form, applet)

oMessages (form, applet)

oOnFormClick event (for form)

•Modal dialogs

•Reference system
