TryTakeToolbar, VIRTUAL
The TryTakeToolbar method returns a value indicating whether the ToolbarTarget object successfully assumed control of the toolbar. A return value of one (1 or True) indicates success; a value of zero (0 or False) indicates failure to take control of the toolbar.
Implementation:
The ToolbarClass.SetTarget method calls the TryTakeToolbar method. The TryTakeToolbar method calls the TakeToolbar and returns True because, by default, a ToolbarUpdateClass object may always assume toolbar control.
Return Data Type: BYTE
Example:
ToolbarClass.SetTarget PROCEDURE(SIGNED Id)
I USHORT,AUTO
Hit USHORT
CODE
ASSERT(~ (SELF.List &= NULL))
IF Id !set explicitly requested target
SELF.List.Id = Id
GET(SELF.List,SELF.List.Id)
ASSERT (~ERRORCODE())
SELF.List.Item.TakeToolbar
ELSE !set a valid target
LOOP I = 1 TO RECORDS(SELF.List)
GET(SELF.List,I)
IF SELF.List.Item.TryTakeToolbar() THEN Hit = I.
END
IF Hit THEN GET(SELF.List,Hit).
END
