IÂ´m coding a little HTML Editor. And now I have a big problem , which doesnÂ´t allow me to go on with working until IÂ´ve fixed it. So IÂ´m gonna ask you for a sollution: I want to draw a block, where you can enter text, like this:

This is a field, where you can enter text. Now I ask you if it is also possible to draw a field like this in PB in a window. I also want to make it possible, that the user can change fonts, sizes, colors and so on. I also want to have the scrollbars on the right side of the field. Is this possible???

All right. IÂ´m not sure how I can enable HTML support for this topic post. Please be so kind and copy the code in an external HTML document and view it with a browser.

Greetings and thanks, merendo

Hi,

If you want the font style to be the same in the whole (this is how it works usually) you can use an Edit control to do that (that is, a multilined StringGadget, I don't know how to do it without CreateWindowEx_()). In any case, you can use the RichEdit library to achieve the desired result (I think it will save you typing).

Feel free to ask for further help. Bye,

I feel.
No, I donÂ´t want the font to be the same in the whole block. I want to have block, where the user can mark text, and press a button. When a such event happens, the font should change only in the marked area. (DonÂ´t know how, f.e.: FontRequester(), and then using the font commands)

Hi,

If you decide to use the RichEdit library to do so, a sample code would be something like:

  SetForegroundWindow_(ParentHandle)
  UseWindow(0)
  SetWindowCallback(@WndProc())

  Repeat
    WaitWindowEvent()
  Until Quit = 1

EndIf

End

Of course, you would have to install the library. It's available at Paul's site:

I would post it at DarkUni's also, but I don't know how.

I hope your project goes Ok, here we are if you need any help.
