contextmenu

问题 Within a TreeView 's resources, I have a HierarchicalDataTemplate that also defines the context menu style. The aim is to be able to have programmatically defined MenuItem s specify an icon name as their Tag and then have the front-end display the right icon. <StackPanel.ContextMenu> <ContextMenu ItemsSource="{Binding MenuItems}"> <ContextMenu.Resources> <Style TargetType="{x:Type MenuItem}"> <Setter Property="Icon"> <Setter.Value> <local:StringToIcon IconName="{Binding Tag, RelativeSource=

问题 I'm looking to create a create a chrome extension which gets the currently highlighted text and creates a div just under the text, like the chrome dictionary app. Does anyone know what sort of popup this is, or how it is achieved?

问题 I'm working on a Cocoa application that has editable text fields. These text fields need to accept values but don't need to be spell checked or use any of the other options given in the default context menu. I've read that the easiest way to remove the right click/ opt + click context menu is to override the function: rightMouseDown:(NSEvent *) I've done this in a custom NSTextfield class. This fix blocks the user from right clicking when the text box is enabled and unselected, but as soon as

问题 I have a listbox with context menu. How can I get value of SelectedIndex (SelectedItem) property in ContextMenuItem click event handler? Currently in events Edit_Click and Delete_CLick a value of CarsList.SelectedIndex always is -1. Here my ListBox in XAML: <ListBox Name="CarsList" Style="{StaticResource ListBoxStyle}" Margin="26,0,26,0" Height="380" > <toolkit:ContextMenuService.ContextMenu> <toolkit:ContextMenu Name="ContextMenu" > <toolkit:MenuItem Name="Edit" Header="Edit" Click="Edit

问题 I have a context menu that needs to use a dark background. It uses a check margin and has several sub-menus. The check mark and the arrow indicating a sub-menu are both black and thus hard to see. I can find no way to change the color. (It would seem obvious to me that they ought to use the ForeColor, which we have set to white for the text, but this does not seem to affect the check marks or arrows.) Is there a way to do this? EDIT: We are using images in the image margin as a work-around.

问题 I'm trying to create a context menu for a list box which displays elements in the context menu from the list box.

问题 I've activity that i want an option menu to be displayed on. But, i want the option menu to be displayed all the time the activity is displayed. I don't want my users to click (select) the menu button to display it. I want it to be there all the time. How can i do it? thanks 回答1: Activity.openOptionsMenu() . From a design standpoint, I have to agree with Mayra. Wrong approach to begin with. 回答2: If you want options to appear at the bottom of the screen always, don't use the options menu. Just

问题 Is it possible to catch a right-click inside of flash (AS3)? No JQuery/JavaScript. I need to pause gameplay when a right-click is caught, so I don't so much want to disable the context-menu as I do just want to tell that a right-click has happened. Is there an EventListener I can add? Any other ideas? UPDATE: I need the event to be triggered as they are actually right clicking, not just after the context-menu has disappeared. 回答1: There are only two ways to capture a right click event: For a
