How to get the text data from the current tab by using some code.

[wochatme]

I am adding some code in NonClientIslandWindow.cpp to response to some windows event such as WM_LBUTTONUP. I want to get the text data from the current terminal window, like a LPCWSTR pointer. I checked the code, and some some useful functions like:

        const auto visible = _GetVisibleViewport();
        const auto top = visible.Top();
        const auto height = visible.Height();

Terminal::TextCopyData Terminal::RetrieveSelectedTextFromBuffer

Now I am blocked how to call these functions from a function responding WM_LBUTTONUP event of NonClientIslandWindow window.

Could someone give me some idea?

Much appreciated!

Sorry, what exactly are you trying to accomplish, big-picture?

The answer here probably changes if you're building something inside the Terminal codebase, vs in another process that's trying to hook the Terminal's wndproc 😉

I add a patch into the code of NonClientIslandWindow.cpp. My requirement is: if the event of WM_LBUTTONUP is triggered, one function is called. Within this function, I want to capture the text data of the current terminal window as LPCWSTR or std::wstring.
