procedure ShowEditorChar(Ch: Char);
void __fastcall ShowEditorChar(System::WideChar Ch);
Displays the inplace editor, with its text set to the specified character.
Grid controls call ShowEditorChar when the user types a character into a cell and the editor is not already showing. ShowEditorChar displays the window of the inplace editor over the currently selected cell, and sets its text property to the character Ch. If the inplace editor does not yet exist, ShowEditorChar creates it.
