Combine Cells? [message #3876]

Is there a way to combine cells eg:
assume this array
---------
| | | | |
---------
| | | | |
---------
| | | | |
---------

and combine two cells in one column:
---------
| | | | |
--| |----
| | | | |
---------
| | | | |
---------

I was unable to find something in the source, so i guess I will have to derive and rewrite some virtual methods like Paint() am i right?

There is no simple direct method.

This is not a typical ArrayCtrl usage scenario, so the first logical question is what you want to achieve? Wink

Anyway, the possible solution is to cancel the grid (ArrayCtrl::NoGrid) and use custom Displays to draw the grid lines where needed. I do not recommend overriding the Paint.

thanks for your answer, Mirek

what i want to achieve is spreading an ctrl over more than one cell, and have horizontal and vertical scroll.
But would like to have the grid as background.
And i would like another "headCtrl" on the left side, not only at the top.

so i guess the best would be to write my own control(s), right?

Yes.

There is a separate discussion thread about "ScrollPane". I guess that is what you need. You can inspire yourself also studying PropertyPane class in ide/LayDes.

Some day something like that will be part of U++ - the obstacle here is to investigate all various usage scenarios, that is why so far we rather prefered to implement specific class for specific usage.
