Freeze selection when OTK ui is launched.

[RS_9601780]

Hi,

I have a UI created for OTK application. There is button which when pressed allows user to select a face which will be processed later. We use pfcSession->select() for selection. Once selection is done, user presses middle click to complete the selection.

User requirement- When selection of the face is completed, by pressing 'Ok'/middle click, I want to stop any further redundant selection. Selection should happen only when pfcSession->select() is On.

Please help.

Thanks

This is how to limit a number of possible selections to 1:

• follow the example in 'Common Files\otk\otk_cpp\otk_examples\otk_examples_feat\OTKXCreateSweep.cxx'
• make sure "surface" option is specified and max number of selections is set to 1.

Without seeing your dialog control loop it is impossible to tell what is 'On' state and what is 'Off' state.

BTW - Pro/Toolkit has enum ProSelectionEnvAttr which alters behavior of interactive selection such as showing Ok/Cancel dialog box, requiring Ok-button-click to finish interactive selection process and so on.
