contextmenu

问题 I have an Intent that extends a ListActivity. In my onCreate method after having populated the list adapter I use registerForContextMenu(getListView()); to register for a context menu. Now it is working and the context menu has its original function which is; once I click and hold down on an item the context menu opens. Can I open the context menu on a single click (without having to hold down on the list)? All help is appreciated. 回答1: call activity.openContextMenu(l) onitem click event to

问题 By default menu items become disabled when its command cannot be executed (CanExecute = false). What is the easiest way to make the menu item visible/collapsed based on the CanExecute method? 回答1: You can simply bind Visibility to IsEnabled (set to false on CanExecute == false). You still would need an IValueConverter to convert the bool to visible/collapsed. public class BooleanToCollapsedVisibilityConverter : IValueConverter { #region IValueConverter Members public object Convert(object

问题 I'm trying to implement pop-up menus in Java JTree. I've sub-classed DefaultTreeCellRenderer (to change node appearance) and DefaultTreeCellEditor (to create Components to attach event listeners to, since apparently the Components that DefaultTreeCellRenderer.getTreeCellRendererComponent() returns can't do it?). I don't really want to "edit" the nodes, just be able to pop-up a menu when a node gets right-clicked, but this is the only way I can think of doing it right now... Below is the code

I want it so that you can be inside the folder, and click a blank part of that folder and get the context menu item

问题 I am using this link from Oleg and Demo to create context menu. Is there a way to pass some dynamic values to each row apart from rowId. May be one way is to set hidden values for each row and get those hidden column values but not sure how to implement this functionality. Thanks for any help or suggestions.. loadComplete: function(data) { // Fix the Grid Width... fixGridWidth($("#grid")); // Context Menu $("tr.jqgrow", this).contextMenu('contextMenu', { bindings: { 'abc1': function(trigger)

问题 my program is based on Google's Hello Gallery example: http://developer.android.com/guide/tutorials/views/hello-gallery.html Instead of using images, I create a bunch of EditText s in the constructor. My question is now: When I long click on an EditText, I want its Context Menu (with "select all", "copy" and so on) to be shown. I've tried setting an OnItemLongClickListener which calls the selected view via myGallery.getAdapter().getView(position, ...).showContextMenu() , but that runs into a

问题 I have a jqGrid for internal use on our site that lists all our users. On each user/row, I would like to be able to apply various options (depending on the data in that row). Instead of adding navbuttons to the pager, it would make more sense to have a context menu that appears on right-click of a row. We currently have this jQuery contextMenu plugin imported on our site, so it would be preferable to somehow integrate that into my jqGrid. My jqGrid scaled down to basics looks something like
