How to disable the default double click callback in a tree table

Hi Yi,

I've not come across anyone asking for this before, and I don't believe there is a built-in way. However, I managed to make a somewhat clunky approach which partly worked. I didn't fully explore to make it fully do what you want though.

The idea is that you define a double click callback yourself and then within that you call something like this:

hiRegTimer(sprintf(nil "(hiExpandTreeItem '%s nil)" treeItem 1) ; treeItem is the third arg of the double click callback

This would always cause them to stay expanded. If you wanted to preserve the status quo, then you'd probably need to define an expandCallback to ?expandCallback on the call to hiCreateTreeTable, and have some mechanism to get your double click callback to record that it was just double clicked and then have the expandCallback determine whether it happened just after (yuck), and if so, re-collapse the field.

Have to use a timer with a delay of 1 because if you use use hiEnqueueCmd it ends up happening too early.

With all of this messiness, I really wouldn't do this - it's highly likely to break at some point even if you can get it to work. If you really need this, I would suggest you contact customer support and request an enhancement that there's a way of turning off the double click expand/collapse behaviour.

Regards,

Andrew.

Hi Andrew

Thank you for the quick reply.

It's good to know there is no build-in way to disable the default double click call back.

I got your ideas and also your concern about it.

I may only apply the double click callback to a leave (not a sub-tree) of the tree table, it may make the situation easier.

or I may consider to use right-mouse button to make a popup menu.

Thank you for your help.

Best Regards

Yi
