Bob et al
I am still in the process of trying to use FTC in an app to replace multiple
text boxes, but continue to struggle.
Following Bob's advice I am trying to use FTCProxy in a single hidden window,
wFTCProxy.
On MouseEnter into a canvas I create a new FTCProxy via
targetProxy = new FTCProxy( CanvasX, wFTCProxy.target)
and use that as the targetProxy for all actions within that canvas.
Prior to creating the new targetProxy, if a previous proxy exists I clear any
selections in that proxy so that they don't reappear in the new proxy and set
the targetProxy to nil.
I also use targetProxy.ftc.getDisplayPicture to grab a picture of the
targetProxy to display in CanvasX.paint when the mouse is not in the Canvas.
Thus, in theory, I end up with one hidden window to provide an FTC control on
demand.
My challenges are now:
1. When taking the picture via getDisplayPicture - it also grabs the Caret if
it is blinking on at the time of the grab. Use of ftc.blinkCaret(true/false)
doesn't seem to be able to turn the caret on or off.
2. When moving into the editor - i.e. a new FTCProxy has been created, I often
get a bleed of the previous canvas' picture showing through the right and
bottom 2 pixels of the canvas being edited, even though both the canvas and the
targetProxy.target have been set to the same size.
3. I seem to be unable to get the insertion point to move to the end of the
current text using ftc.moveInsertionPointToEnd(true) - the insertion point
stays religiously at the beginning.
4. I need to re-adjust the size of the canvas to match the current height of
the text using dim newHeight as double = Target.getdoc.getTotalPageLength. This
works if I stay within one canvas/proxy, but if I move to a new canvas, it
seems to reflect the height of the previous proxy, even though I issue a
targetProxy.update(true) after the targetProxy.ftc.setText ("text").
Note that all the above are in ftc.setEditMode.
Any pointers you might have in solving these issues would be gratefully
received.
