void IconDirectoryView::HandleMessage ( Message * pcMessage )

virtual

Description:: Overload this member to dispatch messages sendt to this handler. When a looper receives a message for one of it's handlers it will call the taget handlers HandleMessage() to allow the handler to dispatch the message.

: The message passed in pcMessage is also available through os::Looper::GetCurrentMessage() and os::Looper::DetachCurrentMessage() until this member returns. This is normally not very usefull for HandleMessage() itself but it can be convinient for other members called from HandleMessage() in case they need data from the message that was not passed on from HandleMessage().

: The looper will be locked when this member is called. The default implementation of this member will pass the message on to the next handler if one was set with SetNextHandler().

Note: Never do any lenthy operations in any hook members that are called from the looper thread if the looper is involved with the GUI (for example if the looper is a os::Window). The looper will not be able to dispatch messages until the hook returns so spending a long time in this members will make the GUI feel unresponsive.

Parameters

pcMessage The message that should be handled. This message will be deleted by the looper when HandleMessage() returns unless you detach it with os::Looper::DetachCurrentMessage(),

void IconDirectoryView::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 IconDirectoryView::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 IconDirectoryView::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.
