How to change Windows Style

[sean345]

I have a rich edit control on my text editor Window. I want to be able to implement a word wrap mode for my text editor. I need to be able to change the window style after the window has been created. I took a look at SetWindowLong, but it does not seem to change the window style. I tried changing window by using the SetWindowLong function but it does not seem to work. I was wondering if I had to call another function after this or if this was the correct function to use.

I tried adding UpdateWindow and ShowWindow afterwards just in case, but it is not working. Does anyone know how to do this?

Thanks

I'm almost certain that you would use SetClassLong() for what you are doing.

I could not get that to work either. What I wound up doing is not the best solution, but still works. I copy the text in the window to a buffer, then close the window and create a new edit control with the correct style. Fill it with the text and it works.

That isn't pretty...What about sending a EM_SETWORDWRAPMODE?

Did you call UpdateWindow after changing the style with SetWindowLong? That might work, doubt it though.

I did try UpdateWindow. It did not seem to work. The EM_SETWORDBREAKMODE documentation says:

This message is available only in Asian-language versions of the operating system.

Thanks anyways.

Sorry about that, I was pulling that off my head instead of looking at the docs. I know this is possible. Can you post some code. Maybe there is something else wrong.

Actually I fixed the problem by destroying the window and creating the new one with the specific window styles. I think this is what notepad does because when there is text present it resets the cursor to the first char no matter where you are just like mine. Thanks for your guy's help.

Generally, use SetWindowLong to change the style bits (GWL_STYLE flag) then use SetWindowPos to update the window. I think any other fn tends to not work or only partially redraws the changes.

Hope that helps.
