在Qt中为应用禁用“开始听写”

Question

Is there a way to disable "Start Dictation" for a mac application? Basically, I am getting "Start Dictation..." menu in "Edit" Menu bar repeatedly. Any work around will be helpful.

Answer 1

Changing the title property of your QMenu will prevent OS X from auto-adding silly things to your Edit menu.

So if I have a QMenuBar and I'm adding menus to it..

m_edit = this->addMenu(tr(" Edit"));

Notice I put a space in front of the text.

You need to rename your menus to stop macOS messing with them. Adding a space in front of the menu item works, but it is a bit ugly. This is a classier way to do it using a zero width character:

menu->setTitle( menu->title().prepend( QString::fromUtf8( "\u200C" )  ) );

You can do it for all your top-level application menus like this in your QMainWindow derived class (tested on Qt 4.7):

#ifdef Q_OS_MACX
foreach ( QMenu* menu, menuBar()->findChildren<QMenu*>() )
{
    menu->setTitle( menu->title().prepend( QString::fromUtf8( "\u200C" )  ) );
}
#endif
