Detailed Description

Description: base class for classes which handle drawing and interaction with cells in the table

Usage: Renderers do the actual drawing of data into the cell (via the 'draw' method) and can allow user interaction with a cell (via the 'buttonEvent' method). When drawing a cell in the table, FWTableWidget ask its held FWTableManagerBase for a FWTableCellRendererBase for that particular cell and then calls the 'draw' method. Similarly, when a mouse button is pressed while the cursor is in a particular cell, the FWTableWidget asks its held FWTableManagerBase for a FWTableCellRendererBase for that particular cell and then calls the 'buttonEvent' method. For efficiency reasons, we encourage the reuse of the same FWTableCellRendererBase instance for multiple cells. The FWTableWidget is written so that it always requests a renderer from the FWTableManagerBase thereby allowing this reuse to work even when the renderer holds state information particular for only one cell (e.g. color).

Classes which inherit from FWTableManagerBase are responsible for creating the appropriate FWTableCellRendererBase for the data held in the table's cells. When the FWTableWidget asks the FWTableManagerBase for a renderer for a particular cell, it is the FWTableManagerBase's job to reset the renderer so that it can properly draw and/or interact with that cell. To allow reuse of the same object, classes which inherit from FWTableCellRendererBase normally have 'setter' methods which are used to set the renderer so it can represent a particular cell.

One inherits from FWTableCellRendererBase in order to provide custom ways to view data in the cell or to customize how users interact with the cell. Inheritance can also be used to allow a renderer to work directly with data held by a FWTableManagerBase.

Member Function Documentation

◆ buttonEvent()

void FWTableCellRendererBase::buttonEvent	(	Event_t *	iClickEvent,
		int	iRelClickX,
		int	iRelClickY
	)

virtual

Called when a mouse button event occurs when the cursor is over a particular cell: arguments iClickEvent: the ROOT GUI event caused by the mouse button iRelClickX: the x position of the cursor click relative to the start of the cell drawing area iRelClickY: the y position of the cursor click relative to the start of the cell drawing area

Reimplemented in FWCheckedTextTableCellRenderer.

◆ draw()

virtual void FWTableCellRendererBase::draw	(	Drawable_t	iID,
		int	iX,
		int	iY,
		unsigned int	iWidth,
		unsigned int	iHeight
	)

pure virtual

Called to draw a particular cell: arguments iID: the id for the drawable in the window. Needed in order to do calls to gVirtualX or to TGFont iX: screen x position that the cell drawing area starts iY: screen y position that the cell drawing area starts iWidth: width (x dimension) of cell drawing area. May be larger than value returned from width() iHeight: height (x dimension) of cell drawing area. May be larger than value returned from height()

Implemented in FWGeometryTableManagerBase::ColorBoxRenderer, FWTextTreeCellRenderer, FWTextTableCellRenderer, FWFramedTextTableCellRenderer, FWColumnLabelCellRenderer, FWCheckedTextTableCellRenderer, and FWCollectionSummaryModelCellRenderer.
