Historically it has been difficult for external testing tools to test C++ panels containing Grids and tool vendors have been forced to use screen scraping / copying to clip board workarounds
But I'm happy to say after working with Mahadev Kanike of CA Support he came up trumps and provided a new event called 'HGM_GETCELLDATA' allowing external testing tools to get grid data with ease at runtime.
"Created a new message "HGM_GETCELLDATA"(its msg ID 1399) to handle by the win-widget grid handler to retrieve the particular cell data by sending row, column details of a grid."
So along with Static control ids we have no excuses not to automate testing our winc panels
I will be posting in the future how to use AutoIt to test a panel
