wpf - What are routed events and how it's different from normal events -


I appreciate if some body can explain with a simple example.

Imagine a window that has a dense hierarchy of hair control. Now we say that you want to do something, there is a right click anywhere in your window.

  • With normal events, you have to handle one click event for all the controls, because you are not sure where the user can click on
  • WPF Together, events are either "bubble" or "tunnel" (i.e. u.iii travels towards the tree or bottom) if they do not find an event handler, which it "handles" at the current level. You can write a handler for the event of the window i.e. TopLevel (Add event to WPF, Preview preview of XXX and XXX - Preview shows the XXX event first and controls the tunnel below the root, which receives excitement and is equivalent to XXX events, then returning from hair control Bubbles up to root) . So if you click on the right button, the WPF visits the UI hierarchy, in which all the handlers are invented, which finds it (unless it marks an event, the "handled" Is.)

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....
