Questions about EM_SETWORDBREAKPROC message and EDITWORDBREAKPROCA function
-
I have created a similar test (although not MFC), and it appears to work. Remember that the callback will not get called until the edit control is trying to reformat some text to fit in the window. I tested mine just by dragging the right hand edge to make the window narrower. As soon as a word needed to be broken, the callback got actioned.
Richard thanks for the help let me explain my problem I am trying to dump data from my z/os machine on a editctrl the data has 0x0a ns 0x0d and 0x0c causing a break where I dont want to I do have a 0x0a 0ad to break a line. need to think If I can use the wordbreak to resolve this issue thanks

I do not think that is what you need. The
EDITWORDBREAKPROCfunction is only called at the point where the control needs to decide whether to split a word or not. Searching for line break characters is a different issue and will depend on exactly how you are trying to reformat it. -

But as I mentioned above, the callback is only actioned when the control is trying to update the display, and a word cannot fit in the existing space. If you do not register a callback then the control will use spaces between words and existing line break sequences. Your issue quite different as far as I understand it, but it is not clear what you are trying to achieve in your text display.

I am trying to display storage from my Z/os Server in the following format a 32 bit address in printable format which is 8 bytes then 16 bytes of storage in printable format 4 groups 4 bytes separated by spaces then within * * the raw hex data at this point i would like to line break I have to look at the streamin says
The control calls the callback function repeatedly, transferring a portion of the data with each call.
just wondering if each call would be a line need to think

I have not used STREAMIN but looking at the documentation at EDITSTREAMCALLBACK (richedit.h) - Win32 apps | Microsoft Docs[^], it suggests that your callback method controls how much, and what format, each block of text takes. So that looks a much better bet than wordbreak.

Richard when while writing my debugger I was display the assembler source code in a richedit I marked off the end of line with /r/n Now I am at the point of display storage did the same typically storage is displayed with printable portion to the left and raw hex data to the right I would mark off the end of each line with 0x0a 0x0d the problem when the raw hex data contains 0x0a 0x0d or 0x0c I am not sure if you return to richedit with what you think is line if it will break that way have to think about this thanks for your help

Hi, If you decide to modify the word/line breaking behavior then it might help to look at how Chromium does it[^]. Richard MacCutchan mentioned modification of the input stream to normalize the line breaks. I think it's worth exploring that idea. Best Wishes, -David Delaune

You should convert the raw data to its hex equivalent (like hex editors do it) so the line breaks do not affect the display.

Richard Siad the wordline break is invoked only what he tried to resize it i.e. once It has been displayed and user narrows the richedit If there is way to invoke the wordlinebreak proc before the display that would be helpful thanks
I am not aware of any way you could do this, since there are no words that need breaking until they are displayed. You may need to consider other options, both of which require you to do all the display handling yourself: 1. Make your display a fixed width based on the font you are using and the amount of data you wish to display. 2. Rebuild the entire display whenever the Window is resized. It may be possible to implement the above by subclassing the RichEdit control, although I have never done that in MFC.

Richard My display is fixed width as it is Courier new I know that exact number of characters in the width of a line (wonder if ShowWindow(SW_HIDE) would drive edit editwordbreakproc) I am just wondering if there is another way and causes line breaks other than 0x0a, 0x0d, 0x0c I have to think about this
