Hi everybody,
I have a hierarchical popup button that should allow me to select a row and
column, both at the same time instead of having to use one popup menu for row,
and one for column
If for example, I select (row, col) = (4,2) as shown, as soon as the mouse is
released the selected item goes back to (row, col) = (1,1) which is what was
checked in IB.
[ 1 ]
[ 2 ]
[ 3 ] [ 1 ]
[ 4 ] > [ 2 ]
[ 5 ] [ 3 ]
[ 6 ] [ 4 ]
[ 7 ] [ 5 ]
[ 8 ] [ 6 ]
[ 7 ]
[ 8 ]
The regular (non hierMenus) popup buttons work great, the Action Methods
trigger correctly, and the window is redrawn with the correct number of rows
and columns.
If you get a chance to look at it, the project download is at :
