TcxHintStyle.EndUpdate Method

Applies all pending changes and redraws the visible hint window after a BeginUpdate procedure call.

Declaration

procedure EndUpdate;

Remarks

Every time you change a hint style setting, the hint controller redraws the displayed hint to reflect the change. Enclose multiple hint style setting changes between BeginUpdate and EndUpdate procedure calls to avoid UI flickering due to excessive redraw operations.

BeginUpdate/EndUpdate and Batch Changes

A BeginUpdate procedure call disables notifications and postpones all changes until an EndUpdate call. A subsequent EndUpdate call does the following:

• Re-enables change notifications and redraw operations
• Applies all changes made after a BeginUpdate call
• Sends corresponding notifications in a batch
• Redraws the visible hint window

Note

Ensure that every BeginUpdate procedure call is followed by an EndUpdate procedure call, even if an exception occurs. Otherwise, the application UI will remain frozen and unresponsive.
