This class does not introduce any new public members. Executing a TdxSpreadSheetIncreaseFontSize action object increases the current font size by one position within the control’s set of predefined font size values. The IncreaseFontSize command is applicable to:

The values displayed in all selected cells.
The text selection within an in-place cell editor (only if the rich content formatting functionality is enabled in the Spreadsheet/Report Designer control).

UI elements linked to a TdxSpreadSheetIncreaseFontSize action object are enabled only if the following conditions are met:

Spreadsheet document editing is allowed (i.e., the control’s OptionsBehavior.Editing property is set to True).
Cell formatting is allowed in the active worksheet (i.e., its OptionsProtection.ActualAllowFormatCells property returns True).
An in-place cell editor is inactive (the active worksheet‘s IsEditing property returns False). This condition is applicable only if the dxSpreadSheetTextService.IsRTFSupported function returns False.

If cell selection is disallowed in the protected worksheet (i.e., its OptionsProtection.ActualAllowSelectUnlockedCells property returns False), executing the TdxSpreadSheetIncreaseFontSize action object has no effect.

Note

If the current font size is equal to or exceeds the largest value in the set of predefined font values, executing a TdxSpreadSheetIncreaseFontSize action object has no effect.
