Member Function Documentation

void TextEdit::Activated ( bool bIsActive )

virtual

Description:: This is a callback member that can be overloaded by derived classes to learn when the view is activated and when it is deactivated. The bIsActive parameter tell whether the focus was lost or gained.

: The view has focus when it is the active view in the active window.

Note:: This is a hook function that is called by the system to notify about an event. You should never call this member yourself.

The window is locked when this member is called.

Parameters

bIsActive - true if the view gain and false if it loose focus.

void TextEdit::FontChanged ( Font * pcNewFont )

virtual

Description:: FontChanged() is a virtual hook function that can be overloaded by inheriting classes to track changes to the view's font.

: This hook function is called whenver the font is replaced through the View::SetFont() member or if the currently assigned font is modified in a way that whould alter the graphical appearance of the font.

Note:: View::SetFont() will call FontChanged() syncronously and will cause FontChanged() to be called even if the view is not yet added to a window. Changes done to the font-object cause a message to be sendt to the window thread and FontChanged() will then be called asyncronously from the window thread when the message arrive. For this reason it is only possible to track changes done to the font object itself when the view is added to a window.

Parameters

pcNewFont Pointer to the affected font (same as returned by GetFont()).

void TextEdit::FrameSized ( const Point & cDelta )

virtual

Description:: Overload this member if you need to know when the view is resized.

Note:: This member is called after the view is resized. If you need the old size you can subtract the cDelta calue from the current size.

Parameters

cDelta The distance the bottom/right corner was moved relative to the upper/left corner.

void TextEdit::MouseDown	(	const Point &	cPosition,
		uint32	nButtons

virtual

Description:: This member is called from the window thread whenever a mouse button is clicked above the view. You can overload this member if your view need to know about mouse-down events.

: A view will not automatically take focus when clicked so if you want that behaviour you must call MakeFocus() from an overloaded version of this member.

: The default implementation of this member will call MouseDown() on it's parent view if one exists.

Parameters

cPosition	Mouse position in the views coordinate system at the time the mouse was pressed.
nButtons	Index of the pressed button. Buttons start at 1 for the left button, 2 for the right button, 3 for the middle button. Additional buttons might be supported by the mouse driver and will then be assigned numbers from 4 and up.

Description:: This member is called from the window thread whenever the mouse is moved above the view or if the view has focus.

: Oveload this member if your view need to handle mouse-move events.

: The default implementation of this member will call MouseMove() on it's parent view if one exists.

Parameters

cNewPos	New mouse position given in the views coordinate system.
nCode	Enter/exit code. This is MOUSE_ENTERED when the mouse first enter the view, MOUSE_EXITED when the mouse leaves the view, MOUSE_INSIDE whenever the mouse move withing the boundary of the view and MOUSE_OUTSIDE when the mouse move outside the view (will only happen if the view has focus).
nButtons	Bitmask telling which buttons that are currently pressed. Bit 0 is button 1 (left), bit 1 is button 2 (right), and bit 2 is button 3 (middle), and so on.
pcData	Pointer to a Message object containing the dragged data if the user is in the middle of a drag and drop operation. Otherwise this pointer is NULL. Look at BeginDrag() for a more detailed description of the drag and drop system.

void TextEdit::MouseUp	(	const Point &	cPosition,
		uint32	nButtons,
		Message *	pcData
	)

virtual

Description:: This member is called from the window thread whenever a mouse button is released above the view. You can overload this member if your view need to know about mouse-up events or if your view support drag and drop.

: If mouse-up was the result of ending a drag and drop operation the pcData member will point to a Message containing the dragged data. Look at BeginDrag() for a more detailed description of the drag and drop system.

: The default implementation of this member will call MouseDown() on it's parent view if one exists.

Parameters

cPosition	Mouse position in the views coordinate system at the time the mouse was pressed.
nButtons	Index of the pressed button. Buttons start at 1 for the left button, 2 for the right button, 3 for the middle button. Additional buttons might be supported by the mouse driver and will then be assigned numbers from 4 and up.
pcData	Pointer to a Message object containing the dragged data if this mouse-up was the end of a drag and drop operation. If no data was dragged it will be NULL.

void TextEdit::Paint ( const Rect & cUpdateRect )

virtual

Description:

Note:

Warning:

Parameters

cUpdateRect A rectangle enclosing all damaged areas. This is just a rough "worst-case", further fine-grained clipping will be performed by the Application Server to avoid updating non-damaged pixels and make the update as fast and flicker-free as possible.
