menu

问题 I have a menu with checkboxes (for example, Settings > Use HTTP/HTTPS/SOCKS5 - 3 different checkboxes) and I want to make it so that when one checkbox is selected others get unselected automatically. My idea was to use some kind of loop to go through each element and unselect them except the selected one. I tried like this: foreach (ToolStripItem mi in settingsToolStripMenuItem) { // code to unselect here } But I can't figure it out. 回答1: In click event handler for sub menu, you can uncheck

问题 I'm trying to create an animated sticky menu. User loads up the page and the navigation is stationary. User then scrolls down the page and after like 500 pixels (scrolling over the original navigation), the navigation animates into the page stuck to the top using fixed positioning. I have it working now (see codepen: http://codepen.io/chrisyerkes/pen/uoFKl) however, once I scroll back up and it resets the menu's position, the next time I scroll down the page, it no longer animates in, just

问题 My problem is simple and I have been unable to find a solution. The menu bar is very annoying in my app and I am hoping that there is a way to remove it. 回答1: Looking at Hiding the Navigation Bar I found this: You can hide the navigation bar on Android 4.0 and higher using the SYSTEM_UI_FLAG_HIDE_NAVIGATION flag. This snippet hides both the navigation bar and the status bar: View decorView = getWindow().getDecorView(); // Hide both the navigation bar and the status bar. // SYSTEM_UI_FLAG

问题 I have an horizontal menu and I want to rotate 90° left or right some of its tabs. Problem is that the transform property also rotates descendants. It looks difficult to put them back in place, is there a solution? P.S. I want to avoid using images or JS, they are ok as fallbacks. 回答1: You could apply the reverse rotation on the descendants. For example div.parent{ -webkit-transform: rotate(-90deg); -moz-transform: rotate(-90deg); } div.parent span{ -webkit-transform: rotate(90deg); -moz

问题 I have made a navbar at the top of my website which contains multiple buttons. One of the buttons right now I added a dropdown menu. It simply uses a unordered list with list items in with a little CSS coding to make it have some colour and actually be hidden until hovered. This works, I have tried it on IE and FF. Both work fine. Now Google Chrome when I try it there, there are some issues. On hover the items appear which they should. But when I try and click on them they disappear. I've

问题 How to achive that following menu act normaly like dropline, but last sublevel to be dropdown instead dropline? Tnx 回答1: To make sure I understand the question, are you wanting the sub-drop-downs to display in a vertical list instead of horizontally? If so, try adding this to your CSS: .droplinebar > ul > li > ul > li > ul > li { float: left; clear: both; } ADDENDUM (to get the menus lined up properly): I haven't tested this, but see if changing line 16 to the following does the trick: $subul

问题 How can I hide the New / Actions / Upload / Settings menus within a list or document library in SharePoint? Note that I need to be able to hide these menus for a particular list definition (template) and not just all lists or document libraries. One possible way that I know of is to register a , and set the ControlClass element to a control that inherits from WebControl. In the WebControl, I can override OnPreRender, which then does this: foreach (Control control in this.Parent.Controls) { if

问题 I am using Pyqt however c++ code is fine. I am trying to change a menu item in QSystemTrayIcon using the QT framework in Linux (Ubuntu 11.10). Currently I have tried to reset the QMenu that I initially set: self.tray = QSystemTrayIcon() m = QMenu() m.addAction('First') m.addAction('Second') tray.setContextMenu(m) I place this in my class and make tray a class variable.
