bool ListView::Invoked ( Message * pcMessage )

virtual

Description:: This member is called from Invoke() just before a message is sendt to the target.

: This allow classes that inherits from os::Invoker to add data to or otherwhice modify the message before it is sendt. The message can also be canceled entirely by returning false from this member.

: The message passed to Invoked() is a copy of the internal message or the message passed to Invoke() (if any) so any changes made here will not affect the internal message or the message passed to Invoke(). When this method returns the message will imidiatly be sendt to the target and then discarded (unless false is returned in which case the message is simply discarded).

: The default implementation of this member does nothing and return true.

Parameters

pcMessage Pointer to the message that is about to be sendt. You can do any modification you like to this message (but never delete it).

Returns: Normally you should return true to indicate that the message should be sendt. You can however return false if you for some reason want to cancel the invokation.

Description:: Returns true if nRow is selected.

Parameters

nRow	Row to check.

void ListView::KeyDown	(	const char *	pzString,
		const char *	pzRawString,
		uint32	nQualifiers
	)

virtual

Description:: Overload this member if your view need to handle keyboard input. This member is called to allow the view to handle M_KEY_DOWN messages. The most common members are exctracted from the message and passed as parameters but you might need to obtain the raw message with os::Looper::GetCurrentMessage() and find some members yourself if you the data you needed are not passed in.

: For example if you need the raw key-code for the pressed key you will have to lookup the "_raw_key" member from the message.

Parameters

pzString	String containing a single UTF-8 encoded character. This is the character generated by the pressed key according to the current keymap accounting for any qualifiers that might be pressed.
pzRawString	Same as `pzString` except that the key is converted without accounting for qualifiers. Ie. if 'A' is pressed while pressing <SHIFT> pzString will contain 'A' and pzRawString will contain 'a'.
nQualifiers	Bitmask describing which qualifiers that was active when the key was pressed.

void ListView::MakeVisible	(	int	nRow,

void ListView::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.

void ListView::MouseMove	(	const Point &	cNewPos,
		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.

void ListView::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 ListView::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.
