menubar

问题 I have a simple vertical one-dimensional menu. Menu items are not fix, they change dynamically according to data received from the server. (So I cannot write fix code for them.) In css I declared selected MenuItem to be bold. My wish is simply to make the selected MenuItem remain bold after selection. But when I click it, it loses focus and the first MenuItem becomes bold. How could that be fixed? 来源： https://stackoverflow.com/questions/14455796/gwt-menuitem-loses-focus-after-selection

问题 We currently have implemented a lot of SWT Actions, because it is a nice way to bind a single command to be added to the menubars and toolbars, and to have Keyboard Shortcuts for these commands. Now... how can I register an Action in plain SWT/JFace without having to add it to a menubar, but in a way that it still can be called by a keyboard shortcut? 回答1: I use to solve this in plain SWT by using Display.addFilter on the KeyDown event. See this question for an example. 回答2: Use the org

问题 I want to achieve the same effect as in Visual Studio 2010+, where if you float an editor on top of the main form, clicking on a main form menu or toolbar button doesn't cause the main form to steal focus; instead the floating window retains focus. Without this it becomes impossible to invoke any main menu command that operates on a focused control when the focused control is in a floating window - because the control you wanted to operate on loses focus just as the command is invoked.

问题 Is there a way in Cocoa to receive a notification (or something similar) when the menu bar becomes hidden or visible? I tried looking around and have not found any information on this topic. Thanks 回答1: I solved this by using Carbon's menu event handlers. I registered for events kEventMenuBarHidden and kEventMenuBarShown under the class kEventClassMenu . 回答2: Optionally watch out for (Cocoa) notifications for an object of class NSStatusBarWindow and notifications like

问题 I've been developing a GUI using PyQt5 and wanted to include a menu bar. When I went to code this feature, however, my menu wouldn't appear. Figuring my understanding on how to implement menu bars in PyQt5 was off, I looked for a pre-existing example online. With some tweaking I developed the following test case: import sys from PyQt5.QtGui import QIcon from PyQt5.QtWidgets import QApplication, QMainWindow, QMenuBar, QAction, qApp class Example(QMainWindow): def __init__(self): super().__init

问题 I have a horizontal menu that is built with an unordered list. On mouseover of one of the list items a submenu will show that is contained within a div. In the submenu while the content displays correctly the div itself is constrained to the width of the parent list item. This results in content overflowing to the right of the div. How can I make it so that div expands with it's content. HTML & CSS on JSFiddle HTML: <div> <ul class="menu"> <li class="menuTab menuTabFirst"> Menu Bar Item 1
