Declaration
function DoUTF8KeyPress(var UTF8Key: TUTF8Char): Boolean; overrideArguments
UTF8Key | UTF-8 character value handled in the method. |
Function result
True if the character was successfully applied in the method.Description
DoUTF8KeyPress is an overridden method used to apply the
UTF-8-encoded character in
UTF8Key to the active cell
Editor for the control. The return value is
True if the
character is successfully handled.
DoUTF8KeyPress calls the inherited method on entry to determine if the character is handled in the ancestor class. No additional actions are performed in the method when the character is handled in the ancestor.
Otherwise, EditingAllowed is called to determine if a cell editor
can be displayed for the column number in Col. When allowed, the
EditorShowChar method is called to apply the value in UTF8Key to
the cell Editor. The value in UTF8Key is set to an empty string (''),
and the return is set to True on successful completion of the
operation.
