TMlSkinSystemButton

Notes

• Kind selects close, minimize or maximize. The component performs the action itself, no code needed.
• The four Image properties supply the close, minimize, maximize and restore icons; a maximize button switches to RestoresizeImage once the form is maximized.

Example

Properties of TMlSkinCustomNCButton 6

Name	Type	Default	Description
AllowAllUp	Boolean	False	Whether all buttons in the group may be up at once. With it off, one button in the group always stays down.
Picture	TPngPictures	—	The image used by the control, given as a resource ID or an image file path.
Cursor	TCursor	crDefault	Mouse cursor shape over the control.
Down	Boolean	False	Whether the button is in the pressed state; combined with GroupIndex it behaves like a toggle or a tab.
GroupIndex	Integer	0	Group number: buttons sharing a number are mutually exclusive, so only one stays down. 0 means no grouping.
Enabled	Boolean	True	Whether the control is usable; when off it greys out and stops responding.

Events of TMlSkinCustomNCButton 1

Name	Type	Default	Description
OnClick	TNotifyEvent	—	Fires when the control is clicked.

Properties of TMlSkinNCCtrlBase 6

Name	Type	Default	Description
About	TMlAboutInfo	—	A design-time property: double-clicking it in the Object Inspector opens the MLSkin about box with the component version. It has no effect at run time and is not stored in the .dfm.
PutSide	TSideKind	skdTop	Which edge of the non-client area the control sits on: skdTop, skdBottom, skdLeft or skdRight.
Tag	Integer	0	A spare integer for your own bookkeeping; the component itself does not use it.
Pos	TNCCtrlPos	—	Position along that edge: an alignment plus X/Y offsets. With UseDefault on, the default layout is used.
Hint	string	—	Tooltip text shown when the mouse rests on the control.
Visible	Boolean	True	Whether the control is visible.

Events of TMlSkinNCCtrlBase 5

Name	Type	Default	Description
OnLMouseDown	TNotifyEvent	—	Fires when the left mouse button goes down on the control.
OnLMouseUp	TNotifyEvent	—	Fires when the left mouse button is released on the control.
OnMouseEnter	TNotifyEvent	—	Fires when the mouse enters the control.
OnMouseLeave	TNotifyEvent	—	Fires when the mouse leaves the control.
OnDPIChanged	TMlDPIChangedEvent	—	Fires when the screen DPI changes, for example when the window moves to a monitor with a different scaling — a good place to re-adjust anything you draw yourself.

Only the properties and events MLSkin adds are listed here. Standard VCL properties such as Align, Anchors, Font and OnClick are available too and behave exactly as on the stock controls.
