TControl.GetTextBuf

Gets text associated with the control from a buffer

Declaration

Source position: controls.pp line 1334

Arguments

Function result

Pointer to the buffer containing the text

Description

* The VCL implementation relies on the virtual Get/SetTextBuf to 
 * exchange text between widgets and VCL. This means a lot of 
 * (unnecesary) text copies.
 * The LCL uses strings for exchanging text (more efficient).
 * To maintain VCL compatibility, the virtual RealGet/SetText is
 * introduced. These functions interface with the LCLInterface. The
 * default Get/SetTextbuf implementation calls the RealGet/SetText.
 * As long as the Get/SetTextBuf isn't overridden Get/SetText 
 * calls RealGet/SetText to avoid PChar copying.
 * To keep things optimal, LCL implementations should always 
 * override RealGet/SetText. Get/SetTextBuf is only kept for
 * compatibility.
