From 342d2a253ca14d9d8dff843f682661d4933d1dd3 Mon Sep 17 00:00:00 2001 From: Alexander Potashev Date: Mon, 9 May 2011 10:39:18 +0200 Subject: [PATCH] Allow different text for undo actions and items in QUndoView Now the texts used for undo actions and for items in QUndoView can be set separately. This introduces an extended format of text that can be passed to QUndoCommand::setText or QUndoCommand constructor. The action text can now contain two strings separated by a "\n". The first string (that goes before "\n") is then returned by QUndoCommand::text() and used as name of item in QUndoView. The second string (that goes after "\n") is returned by QUndoCommand::actionText() and used when the text properties of the undo and redo actions are updated. If the text passed to QUndoCommand does not contain "\n", everything works as before, and both QUndoCommand::text() and QUndoCommand::actionText() return the same string. Even though action text in English usually does not need different forms for undo actions and QUndoView item, translators can employ this new command text format, for example to adjust the grammatical case used in command text to match the context of "Undo %1"/"Redo %1".
