Is there a way to avoid holding the ALT key when cycling through input fields within a SAPUI5 table?

阅读更多关于 Is there a way to avoid holding the ALT key when cycling through input fields within a SAPUI5 table?

问题 I have a SAPUI5 table which contains input fields. I have prepared an example at http://jsfiddle.net/bgerth/x8h92mz8/. When you press ALT+TAB you can cycle through the input fields within the table (I only found that out by looking at sap.m.ListBase.prototype._startItemNavigation ). Only pressing TAB focuses the first element outside the table. I consider that rather non-intuitive. Is there a way to make TAB alone work the same way? Update: Alt+Tab works in Chrome and Safari, but not Firefox

阅读更多关于 Can a Cocoa app's executable steal focus from caller?

问题 Say I have a standard Cocoa Application call Foo.app (like the one you get just by choosing New Project > Cocoa Application in Xcode), if I open the app via a terminal using: open Foo.app/ Then I see Foo's name on the status bar up top and its window is in focus, in front of all other apps.

Rich Text Editor and focus by submit button

阅读更多关于 Rich Text Editor and focus by submit button

问题 I have a textarea to which I associate a Rich Text Editor . I've followed the steps to install it and everything runs smoothly. The textarea in question is within a form with other textarea and fields to be filled out. Clicking on the classic submit button, I set via js that if the field is empty an alert appears and the system puts the focus on the empty element. This does not work with the textarea combined with the Rich Text Editor, obviously because the latter transforms it into a sort of

Removing focus from all objects in Visual Basic 6

阅读更多关于 Removing focus from all objects in Visual Basic 6

问题 Is there a method such that a user can click on the form itself, and in doing so remove focus from whatever object (textbox, combobox, etc) currently has it? Basically, can focus be uniformly removed from everything at once? Setting the focus to the form itself does not work. I thought about doing the old "hide a placeholder button behind another object" trick, but I'm really not a fan of that. Thanks! 回答1: In VB6 a PictureBox can get focus, even if it does not contain any control. In your
