TCustomComboBox.SelectAll procedure

Declaration

procedure SelectAll

Description

SelectAll is a procedure used to select/highlight the Text displayed in the edit box for the control. SelectAll requires a Style that uses an edit box in the control. No actions are performed in the method when Style does not include an enabled edit box.

SelectAll sets the value in SelStart to 0 (zero) to move the selection to the beginning of the edit box, and sets SelLength to the number of UTF-8-encoded characters in Text. No selection/highlighting is performed when Text contains an empty string ('').

SelectAll is called from methods like DoEnter, KeyUp, CloseUp, and MouseUp.
