contextmenu

问题 I'm already able to create a new menu in the top menubar of Outlook 2003 but would like to do the same when the user right-click on an email (but not anywhere else in the interface if possible). Here is what I got: Sub AddMenus() Dim cbMainMenuBar As CommandBar Dim cbcCustomMenu As CommandBarControl Dim cbcTest As CommandBarControl Dim iHelpMenu as Integer Set cbMainMenuBar = Application.ActiveExplorer.CommandBars.ActiveMenuBar iHelpMenu = cbMainMenuBar.Controls("&?").index Set cbcCustomMenu

问题 When I use ContextMenu from Silverlight 4 Toolkit I want to get ContextMenu instance's Owner, but it's not available since in ContextMenu class Owner is an internal property. For example, I have a Rectangle put inside a Border. When I right-click a Rectangle (and a context menu appears) I need to change the Rectangle Border's thickness to indicate that the Rectangle is the current element of the parent Grid, for example. So I try to use ContextMenu.Loaded event where I get the ContextMenu

问题 I want that when I click on a menu item, display a context menu with items such as "delete", "rename", etc. How to bind itself a context menu when you right-click on the menu item? 回答1: The first idea jumping in my mind was hook up some MouseDown event on the ToolStripMenuItem and show the second ContextMenuStrip at the mouse position in screen coordinates. But it's not such simple. The problem is doing so will require hooking up the event for every items, on that event somehow showing the

问题 I am using jQuery context menu plugin by Chris Domigan to appy a context menu. This is how it works: $('#contacts tbody tr').contextMenu('myMenu1', { bindings: { 'copy': function(t) { alert('Trigger was '+t.id+'\nAction was Copy'); }, 'delete': function(t) { alert('Trigger was '+t.id+'\nAction was Delete'); } }, }); Now I want this context menu to appear on left click instead of right click. I can not find an option in the doc. Any ideas how to do that? Do I have to modify the source? 回答1: As

问题 My issue is a kind of follow up of this question I would like to get the widget which has been right clicked to do an action on it. Conditions : right click on "my label 2" select "Display the label" Expected results : => "my label 2" should be printed Initial code to solve : from Tkinter import * # Tkinter -> tkinter in Python 3 root = Tk() def print_label(): print "Please, help me to print the label which has been clicked !" def popup(event): menu.post(event.x_root, event.y_root) # create a

问题 I'm creating a detailed static cascading context menu for ImageMagick in Windows... Everything seemed to be working well functionality-wise until I passed 20 items with the context menu. After that, clicking on commands stopped functioning properly and items disappeared. (I know its not a formatting issue because I can bring them back by deleting higher up items) There was plenty of space on my screen with my organization scheme... They only disappeared because of an unneeded limit! Does

问题 I have this Tree View that looks like this: <TreeView Grid.Column="0" Grid.Row="2" MinHeight="100" MinWidth="100" BorderBrush="White" DataContext="{Binding Projects, Source={x:Static SizingApp:Manager.Instance}}"> <TreeView.Resources> <Style TargetType="TreeViewItem"> <Setter Property="IsExpanded" Value="True" /> </Style> <DataTemplate x:Key="LoadTemplate"> <TextBlock Text="{Binding Name}"> <TextBlock.ContextMenu> <ContextMenu> <MenuItem InputGestureText="{Resx ResxName=PSSPECApplication

问题 I just spent the last hour on trying to find out why the hell my PATH variable wasn't updating for my cmd.exe. Now I figured out that it kind of did update, but only for certain conditions... I updated it via Win+Break -> Change Settings -> Advanced -> Environment Variables... Now when I open a new commandline via Win+R -> cmd -> Enter the PATH variable shows whatever I set it to. But when I open a new commandline via Shift+Rightclick into folder -> Open command window here , the PATH

问题 I have a couple of QDockWidgets that are all not closabale (using Qt 5.6). Therefore, the context menu that is displayed when right-clicking a title bar of one of them only has disabled entries, and I would like to disable the whole context menu. I tried to set the contextMenuPolicy to NoContextMenu without success. I then tried to use a subclass of QDockWidget, override the ContextMenuEvent and ignore it. The menu is still displayed. I then tried to install an event filter to catch the

问题 How do I disable the context menu in the IE WebBrowser control and instead perform custom handling of the right-click event in C#? 回答1: Actually: WebBrowser browser; browser.IsWebBrowserContextMenuEnabled = false; This pretty much tells the WebBrowser that the right-click context menu is not welcome. 回答2: WebBrowser browser; browser.Document.ContextMenuShowing += new HtmlElementEventHandler(MyCustomContextMenuMethod); 回答3: AddHandler Me.WebBrowser1.Document.ContextMenuShowing, AddressOf
