Description

The bBrowser supports several modes for ToolTips. The following table defines the supported modes:

Mode	Description
#Control	For the whole bBrowser, only one ToolTip is supported. The ToolTip can be defined with the access Control:ToolTipText.
#Column	Each column will have a unique ToolTip. The ToolTip for the column is determined with the callback method CellToolTip().
#Cell	Each individual data cell will have a unique ToolTip. The ToolTip for the data cell is determined with the callback method CellToolTip(). Notes! Before the callback method CellToolTip() is called, the following check is executed: If the ToolTip should to be determined for a column value and the column value is not completely visible in the cell then the column value is used as ToolTipText as default. The ToolTipText can be replaced by another text in the callback method CellToolTip() (see also bCellToolTipEvent:ToolTipText).
#CellRegion	Each individual data cell can have several ToolTips depends on the position of the mouse. The ToolTip for the data cell is determined with the callback method CellToolTip(). Notes! See also the notes of mode #Cell. The position of the mouse can be determined with the access bCellToolTipEvent:Position.

After creating a bBrowser control the mode #Control is active.

Samples

In the following sample for each data cell a different ToolTip is shown. As ToolTip the HyperLabel of the column and the column and row number of the data cell is shown.
