command

问题 The ListBox control does not implement a Command property. I have to attach some functionality to the SelectionChanged event. Somebody knows how can I do it? Please help me 回答1: I prefer using a binding to the SelectedItem and implementing any functionality in the setting of the binding property. <ListBox ItemsSource="{Binding Items}" SelectedItem="{Binding SelectedItem}" /> ... public class ViewModel { public IEnumerable<Item> Items { get; set; } private Item selectedItem; public Item

问题 Question: How could I find out the M-x equivalent commands for doing GUI-based operations in Emacs, in those cases where my Emacs-variant uses OS-specific desktop functionality? Background: Conventional understanding states that everything in Emacs is a command, and that commands can be invoked via M-x, as long as you know the name of the command. Assuming this statement is correct, what is the way to find the name of the commands used to trigger the "GUI-style" menus in a "desktop" based

问题 I have tried to use delphi to send commands to the command prompt. However, i am not able to do so as i used CreateProcess method to do it. I have tried to change the StdOutPipeWrite, however, the CreateProcess seems to not allow commands after the initial command from CreateProcess to be passed through.

问题 If I have a file that contains a complete path for a file, is there a way to highlight the filename (using visual mode) and open the file (preferably in a split screen)? Here is the behavior I would like: if the file name contains a / character, assume it is a full path (i.e. the current directory is root). Otherwise, use the current folder (i.e. default behavior). Is this possible? 回答1: Put the cursor on the filename and type gf (in command mode). Or use CTRL + W | CTRL + F to open in

问题 I'm struggling to understand what is going on with the ContextMenu. I know it is rendered as a separate window, with a separate visual tree, so we can't use relative binding to bind a command exposed as a property of the user control. e.g. the following does not work: <MenuItem Command="{Binding RelativeSource={RelativeSource AncestorType=UserControl}, Path=TestCommand}" Header="Test" /> But, if you set the data context of the user control to a view model that exposes a command as a property,

Basically the problem I am having is that I have a TreeView (System.Windows.Controls.TreeView) which I have placed on my WPF Window, I have decide that I will bind to a ReadOnlyCollection of CommandViewModel items, and these items consist of a DisplayString, Tag and a RelayCommand. Now in the XAML, I have my TreeView and I have successfully bound my ReadOnlyCollection to this. I can view this and everything looks fine in the UI. The issue
