Questions about tstringgrid

[rchastain2]

I am starting a new project: a GUI displaying a computer analysis for a chess game.

I load the moves of the game in a tstringgrid. The user should be able to navigate through the game, using keyboard arrows or buttons. The GUI will display the chessboard after the move, and other things related to the selected move.

In the attached demo, I think I have the solution to navigate by keyboard or buttons. But I don't know how to get cell coordinates if the user selects a move by clicking in the grid.

It's my first question.

Hello Roland!

You may use tstringgrid.oncellevent() for this:

Hello Fred. It works perfectly. Thank you!

Now, I search how could I improve the appearance. If you have ideas...

For example, how could I change the background color of the selected cell?

Hello Roland.

You can do this by assigning a color to datacols.colorselect and (if you want the selected font to have the same background color as the cell) to datacols.fontselect.colorselectbackground + black (or white if the background is dark) to datacols.fontselect.colorselect.

Then, in tstringgrid.oncellevent(), add if info.eventkind = cek_focusedcellchanged then grid.selectcell(info.cell, csm_select, false);.

Great! Works perfectly.

Note that you may assign fontselect.colorselectbackground := cl_transparent, it works too.

Thank you, Fred. I think I have all what I need for my project.

Maybe I will make a tutorial about tstringgrid, using your answers and the following examples:
