I'm getting an error using some datagrid drag and drop handlers provided
for datagrids. The error happens when I drag a line outside the boundaries
of the stack window and then back in again. So far I can only make this
happen in a standalone program, not the IDE.
The standalone reports the folloing error:
Type: Chunk: error in object expression
Object: button 'dgTrackDragDrop' of group 'ColumnList' of card id 1002 of
stack 'SQLiteAdmin_CreateNewIndex' of stack
'/Applications/SQLiteAdmin.app/Contents/MacOS/SQLiteAdmin'
Line:
Line Num: 24
Hint: dragMove
The handlers I'm using look like this:
*on* dragStart
*local* tTheIndex, tTheDragData, tTheDataControl
*put* the dgDataControl of the target into tTheDataControl
*if* (tTheDataControl is empty) *then* *pass* dragStart *-- Prevent the
move if no data control exists*
*if* (the dgHeader of the target is empty) *then*
*put* the dgIndex of tTheDataControl into tTheIndex
*set* the dgDragImageIndex of me to tTheIndex
*set* the dragData["private"] to tTheDragData
*set* the dgDragReorderData of me to tTheDragData
*set* the dgTrackDragReorder[tTheIndex] of me to true
*end* *if*
*end* dragStart
*on* DragReorderDrop pOriginatingIndex, pStartLine, pDroppedOnLine
*if* (pStartLine is not pDroppedOnLine) *then*
SetLineOfIndex pOriginatingIndex, pDroppedOnLine
*send* "RefreshList" to me in 0 secs
*end* *if*
*end* DragReorderDrop
*on* dragMove
*local* tTheDragData
*put* the dgDataControl of the target into tTheDataControl
*if* (tTheDataControl is empty) *then* *pass* dragMove
*set* the dragaction to "move"
*put* the dgIndex of tTheDataControl into tTheIndex
*-- set the dgDragReorderData of me to tTheDragData*
*set* the dgTrackDragReorder[tTheIndex] of me to true *-- Scroll the
list during the dragMove using the datagrid API*
*
*
it looks like th error is in a datagrid internal handler but I haven't been
able to track it down. Has anyone else experienced this?
