c# - width of the dropdown arrow -


Then in the winforms, each dropdown combo box has this small arrow object on the right that tells the user that it is a dropdown Just like this:

Now how can I find out the width in pixels? The reason for this is, I am using ControlDrawToBitmap, it does not properly draw text for the combo box, and I can undo the content again, I want to fix some arrows (which are properly prepared ) The first idea that comes to mind: Check to see if the width of the compose button is to increase the width of the scrollbar width.

With Tracks. Use the GetSystemMetrics () API to get the width of different scrollbar pieces, which can be modified scrollbar width in user preferences. If you change the width of your system scrollbar and it does not affect the normal combo box size, then ignore it.

The second idea: to use the reset formatting of the edit controls to see what the editing controls think about the display area (less combo box).

However, it seems that this is the only solution to a hack for your real problem: If you can control the control properly in bitmap, you will not need this hacker.

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....
