Is there anyway to store and then restore the scrolled to position in a wxTextCtrl? Not the HTML one, but just the text one.
Something like STC’s GetFirstVisibleLine, but for wxTextCtrl?
Thanks.

Yeah, that’s the function I would use if I had pos, but I don’t and that’s the problem. Is there a way to see which pos is
in the upper left corner? The position would be preferable, but I might
be able to make do with the line. Or maybe even the scrolled amount.
But I don’t know that you can correctly manually scroll a TextCtrl.
Any ideas on how to get the proper pos?

So no GetFirstVisibleLine type command for TextCtrl? Isn’t there some way to just grab the first line from the windows, etc?
Anyone?

OK, just to partly answer my own question.
I did the following:
scroll = self.GetScrolledPos(wx.VERTICAL)
This gets me the scrolled position in pixels, I believe. I then, by
trial-and-error, found that the number of pixels in one LINE of
scrolling is 19.
So then I did:
self.ScrollLines(scroll/19)
Is there a surefire way to get the exact height of a scroll line in pixels? Seems like there should be, based on the font, etc.
How do you get the height of a scroll line in pixels?

Hello Josh,
you can try something like:
linewidth, lineheight = MyTextCtrl.GetTextExtent(“Aq”)
Then you can use the lineheight result to see if it is closer to 19 or not.
HTH.

Maybe this can do the job:
def GetFirstVisibleLine(self):
res, col, row = self.txt.HitTest((0,0))
pos = self.txt.XYToPosition(col,row) + 1
self.txt.ShowPosition(pos)

Maybe this can do the job:
def GetFirstVisibleLine(self):
res, col, row = self.txt.HitTest((0,0))
pos = self.txt.XYToPosition(col,row) + 1
self.txt.ShowPosition(pos)
Oh, you were close. I remembered that HitTest returns the row and
column for the text and is not in pixels for TextCtrl. So, the answer
is:
def GetFirstVisibleLine(self):
res, col, row = self.txt.HitTest((0,0))
return res+row
It’s res+row instead of just row because both no scrolling and one
scroll makes row = 0, whereas res = 1 after the first scroll. Kind of
odd but it works.

Thanks Andrea, I’ll hold on to this for future reference if I have problems with HitTest(0,0).
