contextmenu

问题 I get the following warning and stack trace when I traverse to a screen containing a WebView in my javafx application. However the WebView is displayed and works fine. fxml tag <WebView fx:id="webViewId" contextMenuEnabled="false" focusTraversable="false" layoutX="115.0" layoutY="255.0" prefHeight="210.0" prefWidth="280.0" visible="false" /> Stack trace WARNING: Failed to set class javafx.scene.web.WebView.contextMenuEnabled using class javafx.scene.web.WebViewBuilder java.lang

问题 I read that the context menu should appear centered automatically, but my context menu changes positions based on where I click. This is what happens when I click on the first list item (menu in the lower right corner), and this is what happens for the other items. Here is my code: @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); AdapterView.AdapterContextMenuInfo info = (AdapterView

问题 I want to create a context menu that support multiple files. I read through SO and understand that either you must use DDE or shell extension (something to do with creating and registering COM object). However all the sourcecodes I found are in C#. I then decided to go with COM object. I found 1 in C++ that uses COM but it's dated 2006, so I just don't know if it's outdated. http://www.codeproject.com/KB/shell/shellextguide1.aspx Can anyone shed me some light on this? And is there any good

问题 I have a gridview in an activity where I am trying to display a contextual menu each time a grid element is tapped. I want this contextual menu to display a dynamic value in a textview (the position of the tapped grid element). I am creating my own contextual menu because I don't want an alert or the default android contextmenu. Also I am using SDKs: <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" /> Here is my java.class for the gridview public class Grid_Items extends

问题 There is an event which is dispatched when the context menu (right click menu) in actionscript for flash has been opened: ContextMenuEvent.MENU_SELECT Now, is there an event which is dispatched when the menu has been closed? 回答1: Good question. That would make a nice feature request, an ContextMenuEvent.MENU_CLOSED event :) I think I have half you're answer. Here's my idea: var myContextMenu:ContextMenu = new ContextMenu(); var menuLabel:String = "Custom Item"; var rightClicking:Boolean;

问题 I'm using WPF with C#. I have a grid of buttons and I've assigned a context menu to each button if it's right-clicked. Right-clicking the buttons works fine and the context menu shows up but clicking the menu items gives a null sender. What could be wrong? Here is the relevant code embedded into the Window XAML code: <Window.Resources> <ContextMenu x:Key="cmButton"> <MenuItem Header="Copy" Click="Copy_Click" /> <MenuItem Header="Cut" /> <Separator /> <MenuItem Header="Paste" Click="Paste

问题 In my WPF app, when a ContextMenu is opening, I want to tweak its menu items depending on whether or not the Alt key is pressed. I've got the logic working. XAML: <my:Control ContextMenuOpening="MyContextMenu_Opening" /> Code: private void MyContextMenu_Opening(object sender, RoutedEventArgs args) { bool isAltDown = Keyboard.IsKeyDown(Key.LeftAlt); /* tweak menu items here */ } My problem is that when the Alt key is pressed, the context menu opens and then immediately closes (I can see in the

问题 I want to create an .msi installer that will add a cascading context menu when I right-click my mouse on my desktop. First, I tried doing this using the following script, and this works fine: [HKEY_CLASSES_ROOT\DesktopBackground\Shell\MyApp] "MUIVerb"="My Application" "SubCommands"="app1;app2" "Position"=- [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\CommandStore\shell\app1] @="Run App1" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer

问题 I have a Windows Form program for contact list. I already have a context menu used for copy and pasting from the DataGridView. However, I want to be able to right click a Label and select copy from a context menu to copy the data from that ONE Label. I have 10 different Labels, I do NOT want all of them, just the one that I right clicked on to select copy. I know that using Clipboard.SetText(label1.text) will let me select that specific Label, but I do not what to create 10 context Labels

问题 Thought of asking because never done this before on a TextBlock. I Am not able to copy the content of the DataGridTemplateColumn where it has a TextBlock in that and i have assigned a context menu to that. The copied content is blank. When I tried in MS word is Blank Cell. My Template Column and ContextMenu are as below. I Tried using TextBox But it work when the textbox is enabled and in-spite of grid column is readonly. It allows editing and when we disable it won't copy the text.
