TCustomForm.FFormBorderStyle variable
The border style affects the title bar, border, icon(s), and resize behavior for the form.
Declaration
FFormBorderStyle: TFormBorderStyleDescription
BorderStyle is a
TFormBorderStyle property used to
control the appearance of the border on a form. The default value is bsSizeable
and displays the standard border for a sizeable window. But it could, for
example, be a dialog form or a tool window, or could be non-sizeable. See
TFormBorderStyle for the enumeration values allowed in the property and their
meanings.
Changing the value for the property causes other properties in the form instance to be updated:
- AutoScroll
- Disabled when the property contains a value other than bsSizeable or bsSizeToolWin.
- BorderIcons
- Updated at run-time when the new property value requires a different set of default border icons than the previous value.
- Icon, SmallIconHandle, BigIconHandle
- Updated at run-time by performing the CM_ICONCHANGED control message.
- Menu
- Updated at run-time to create (or re-create) the window handle for a TMainMenu instance using the Handle for the form.
In TCustomForm (and TForm), BorderStyle is slightly different (has a different
base type) from the TCustomControl.BorderStyle property. When the
form is put into another control the window borders depend on the widgetset.
There are no borders under GTK.
This description is the one of Forms.TCustomForm.BorderStyle.
