menu

问题 I've been fiddling with android, and I've been following the menu sample, and it runs almost fine, but the "title" field of the menu items isn't displaying. I think it's related to this question: https://stackoverflow.com/questions/3286093/android-menu-item-not-showing-text but I'm not sure what his answer means. Anyway, it properly gets that I have 2 menu items, it just isn't displaying the text. I'm not quite sure where the error is and figured extra sets of eyes would be good. XML: <?xml

问题 I hope you can help me, I have a leaked window as soon as I exit my application via the (popup) menu option in the toolbar. If I exit the app through a normal method everything is fine. Could somebody maybe help? I cannot seem to find the error and I am trying to find a proper solution. I have 2 static String variables declared but that cannot be the problem I guess. Many thx in advance. Here is the relevant code for the menu: public class LoginActivity extends AppCompatActivity { // private

问题 I noticed a really strange behaviour with menu accelerators on the JavaFX (system) menu. Some key combinations don't work at all and others are interpreted as the wrong key. For instance, when you use the CMD+CLEAR key as accelerator, it gets changed as the CMD+Page Down down key (both in the menu text and in the actual response to a keyboard event). The '-' (MINUS) key doesn't work well at all and while, CMD + - shows up well in the menu, it never gets triggered when you press the keys. When

问题 Is there a way to have a user menu that changes according to the permissions assigned to the user group a user belongs to? I am thinking of something that checks for these permissions at the view level, and also removes menu options a user does not have permission to. 回答1: Yes it is possible to access the user object in the template and check if the user is staff like this: {% if user.is_staff %} <li> <a href="/admin/">Admin</a> </li> {% endif %} This would be an example where your menu where

问题 I have been struggling with the WPF Menu and I simply cannot achieve what I want to. I tried changing default styling on the Menu and MenuItem control, but this turned out terrible. I then tried styling it by making use of control templates, however, I think I came to realization that my WPF skill just aren't there yet. Here is a picture of my desired result: Is there anyone that can maybe point me in the right direction? Or maybe assist me with some xaml that will give my desired result? 回答1

问题 Applications written in Qt (4) do not have native menus when run on Windows 7, 64-bit. This is true for well-known applications as VLC, Lyx, etc. Qt menus do not behave as native menus, which can be annoying. As an example, consider the screenshot below. If the mouse is rapidly moved along the red path, the sub menu will close immediately. For native menus in Windows (and on Macs) there is a delay. This can make it difficult to navigate in the menus, as they will not behave as the user

问题 I have a script for OS X 10.5 that focuses the Search box in the Help menu of any application. I have it on a key combination and, much like Spotlight, I want it to toggle when I run the script. So, I want to detect if the search box is already focused for typing, and if so, type Esc instead of clicking the Help menu. Here is the script as it stands now: tell application "System Events" tell (first process whose frontmost is true) set helpMenuItem to menu bar item "Help" of menu bar 1 click

问题 I work with python-telegram-bot and try to build a system of nested menus as BotFather bot does. For instance, you have a general bot menu where you can choose "Edit Bot" and get the new corresponding menu with an option to get back to the previous menu. I try to achieve that with code: # main menu def start(bot, update): menu_main = [[InlineKeyboardButton('Option 1', callback_data='m1')], [InlineKeyboardButton('Option 2', callback_data='m2')], [InlineKeyboardButton('Option 3', callback_data=

问题 What are the differences between .ContextMenu and .ContextMenuStrip in Windows Forms? I already know what a ContextMenu is, but how is ContextMenuStrip different from ContextMenu ? 回答1: http://www.informit.com/articles/article.aspx?p=606224&seqNum=2 You might wonder why Microsoft has replaced a valuable and popular control with a newcomer. The ContextMenuStrip control takes a good idea and makes it better. It works just like the ContextMenu control. You still attach a ContextMenuStrip control
