wpf - Replace RichTextBox's ContextMenu -


Using .NET 4 and VS2010 Pro, I have created a very simple WPF application, in which the main XW contains the following XAML:

& lt; Grid & gt; & Lt; RichTextBox x: name = "rich textbox" margin = "2" /> & Lt; / Grid & gt;

All I want to do, and have failed to do so by now, the context menu for the richxbox is to take my own place. I've tried code-behind without any luck:

public
{MainWindow} {InitializeComponent (); RichTextBox.ContextMenuOpening + = New ReferenceManageHandler (Rich TextboxContactsMenuoping); } Private Zero Rich TextBox_ContextMenuOpening (Object Sender, ContextMenuEventArgs E) {RichTextBox RTB = Sender as Rich Textbox; If (RTB == tap) {return; } ContextMenu contextMenu = rtb.ContextMenu; ContextMenu.Items.Clear (); Menuimemail = new menu item (); MenuItem.Header = "test"; ContextMenu.Items.Add (MENUITEM); ContextMenu.PlacementTarget = rtb; ContextMenu.Placement = PlacementMode. Relative point; Text pointer status = RTB Selection. the ending; If (condition == blank) {return; } Shape positioning = position GETCharacterRect (LogicalDirection.Forward); ContextMenu.HorizontalOffset = positionRect.X; ContextMenu.VerticalOffset = positionRect.Y; ContextMenu.IsOpen = True; E.Handled = True; }

The harm I am doing is not doing properly. Is its mouse mode being caught by event RTB? Do I have to get my own version of RTB and open the context menu to work it out? It really looks like something, but I'm not seeing it.

Thanks in advance. Rich Textbox X: "Rich Textbox" margin = "2" & gt; ">

& lt; RichTextBox.ContextMenu> & lt; ContextMenu / & gt; & lt; /RichTextBox.ContextMenu> & lt; / RichTextBox & gt;

Rich There is a logic for supplying the contextual menu with things like the base class of the textbox, the logic and the paste in the textboxbox. This logic handles handled as ContextMenuOpening, so your handler has not been implemented. Scope The RichTextBox even empty Info menu, it will leave alone your context menu and open your handler.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
