Detailed Description

An interface object that represents a static text interface element.

Static elements consist of text or graphics that the user does not change. An application, however, can modify the static control. You must use a TStatic object, for example, to create a static control that's used to display a text label such as a copyright notice in a parent TWindow object. TStatic can also be used to make it easier to modify the text of static controls in TDialog objects. See the sample program in the EXAMPLES\OWL\OWLAPI\STATIC directory for an example of a static control.

Constructor & Destructor Documentation

TStatic() [1/5]

owl::TStatic::TStatic	(	TWindow *	parent,
		int	id,
		LPCTSTR	title,
		int	x,
		int	y,
		int	w,
		int	h,
		uint	textLimit = 0,
		TModule *	module = nullptr )

Constructs a static control object with the supplied parent window (parent), control ID (Id), text (title), position (x, y) relative to the origin of the parent window's client area, width (w), height (h), and default text length (textLimit) of zero.

By default, the static control is visible upon creation and has left-justified text. (Set to WS_CHILD | WS_VISIBLE | WS_GROUP | SS_LEFT.) Invokes a TControl constructor. You can change the default style of the static control via the control object's constructor.

TStatic() [3/5]

owl::TStatic::TStatic	(	TWindow *	parent,
		int	resourceId,
		uint	textLimit = 0,
		TModule *	module = nullptr )

Constructs a TStatic object to be associated with a static control interface control of a TDialog object.

Invokes the TControl constructor with similar parameters, then sets TextLimit to textLimit. Disables the data transfer mechanism by calling DisableTransfer. The resourceId parameter must correspond to a static control resource that you define.

Transfer()

uint owl::TStatic::Transfer ( void * buffer, TTransferDirection direction ) -> uint

overridevirtual

TWindow override Transfers TextLimit characters of text to or from a transfer buffer pointed to by buffer.

If direction is tdGetData, the text is transferred to the buffer from the static control. If direction is tdSetData, the static control's text is set to the text contained in the transfer buffer. Transfer returns TextLimit, the number of bytes stored in or retrieved from the buffer. If direction is tdSizeData, Transfer returns TextLimit without transferring data.
