  • what version of wx? OS/toolkit? Did you look at the samples/docs? – Igor Nov 04 '17 at 17:43
  • @Igor I'm using last version on Mac , Linux and Windows. Yes, I look sample. But on sample no exist any example of this. Only read/insert on whole document. Not specyfic line. How determining which line I am? – Marek Kaski Nov 04 '17 at 18:30
  • how read m_curCol ? – Marek Kaski Nov 04 '17 at 21:28
  • did you try GetInsertionPoint()? It is available for wxTextCtrl. The documentation gives the sample code on using the function. – Igor Nov 04 '17 at 22:49
  • yes, not working long line, column, pos = GetInsertionPoint(); PositionToXY(pos, &column, &line); wxPrintf(wxT("%ld(%ld,%ld)/%d: [%s]\n"),pos,line,column, GetNumberOfLines(),GetLineText(line)); I get >7(140732714745280,4513249792)/5: [] – Marek Kaski Nov 06 '17 at 13:31
  • how long is the big line? 100 chars? 1000 chars? Where is the cursor at the time of the call? At the end? Middle? Do you have a sample or a patch to the text sample? Can you upload it here so I can test it? Thx. – Igor Nov 06 '17 at 14:20
  • I have only 4 chars in one line. This is whole document in example. And this is show GetInsertionPoint() – Marek Kaski Nov 06 '17 at 18:13
  • `text` sample has a demo on how to use the `GetInsertionPoint()`. Does it work for you? If not - which OS is failing? In a sample you just press F1 and the message box will display the info. Please try all 3 major platforms with the sample and report back. Thx. – Igor Nov 06 '17 at 18:33

  • documentation doesn't mention anything about OSX restrictions. Which version of the library you are using? – Igor Nov 06 '17 at 18:34
  • @Igor PositionToXY() always returns FALSE on wxMac at least in 2.4.2. This function is not implemented on that platform. PositionToXY()/XYToPosition() also is not implemented on wxMac 2.6.3 and 2.8.0 https://wiki.wxwidgets.org/WxTextCtrl – Marko Lustro Nov 07 '17 at 15:00
  • I checked the HEAD docs. But yes - you are correct. There was a recent patch applied with the proper implementation. It will probably be backported to 3.0 by the time it will be 3.0.3. – Igor Nov 07 '17 at 15:34
