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.

See if this will help you:

#wxtextctrlshowposition

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. 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?

K, 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.

Andrea.

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)

, 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).
