發現，主FORM 定義的快捷鍵，在二級FORM里也有效。

?

反過來，就無效。

?

這樣的話，就要考慮 快捷鍵的沖突問題 了，本來以為不同的FORM 是獨立的。

Quite a bit of the VCL behaviour is dictated by the requirements of the IDE...To fix this problem you have to override the main form's IsShortcut method, like this:publicfunction IsShortCut(var Message: TWMKey): Boolean; override;function TMainform.IsShortcut( Var Message: TWMKey ): Boolean; beginif Screen.Activeform <> self thenResult := falseelseResult := inherited IsShortcut(Message); end; This way the main form will only process shortcuts when it itself is the active form.-- Peter Below (TeamB) Don't be a vampire (http://slash7.com/pages/vampires), use the newsgroup archives : http://codenewsfast.com http://groups.google.com
