void ListViewCol::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.

void ListViewCol::Refresh

(

const Rect &

cUpdateRect

)

void ListViewCol::MouseDown	(	const Point &	cPos,
		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.

void ListViewCol::MouseMove	(	const Point &	cPos,
		int	nCode,
		uint32	nButtons,
		Message *	pcData
	)			[virtual]

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.

Reimplemented from os::View.

void ListViewCol::MouseUp	(	const Point &	cPos,
		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.
