Thanks,
I think i get the point, but, there is still something missing for me to
understand:
1. I understand that (0,0) is now the "top left" of the graphic part, but, it
is still not at the top most (Y coordinates) of the frame. i mean that the
chart is not "attached" right below the toolbar, but 2 units below it (the unit
displayed on the status bar).
2. When i stretch the frame (resize it), i would like the graphic to stretch
with it as well...
3. I tried to change the distance between lines to 2 units (self.SpaceWidth = 1
-> self.SpaceWidth = 2), in that case, it looks as if the whole graphic
"shrinks". I want a bigger distance between two lines, but, keep the proportion.
before i countinue, i want to clarify exactly what my app should do (related to
the chart example):
1. The list on the left (labels) can be very long (about 200 events), so, in
my application now, there is a scroll bar, keeping always the same number of
events in the frame.
2. The same applies to the number of "frames". there can be hundreds of them,
and i need to have the ability to scroll horizontally between frames. In this
case i have ZoomIn and ZoomOut buttons which changes the number of frames i can
see without scrolling (in the chart example, i see two "frames" and i would
like to scale the graphic area to view 4 "frames"...)
3. For future use, i wonder if it's possible to stand on one of the labels (i
know that there is the clickable option and i saw in the examples that it's
possible to delete polygons etc) and to delete this whole event (for example,
remove the "Set RX Rf" event for the canvas). after the deletion there
shouldn't be space or blank, i need the rows to "re-fit"
I hope i'm not asking too much,
I would really want to do this with python (and Float Canvas),
So, again, thanks for any help.
