[PATCH v4 0/4] MR10104: user32/edit: set bCaptureState flag after SetCapture()
Edit control does not release mouse capture after WM_LBUTTONDOWN has been processed two times in a row. This MR fixes this issue by releasing capture and setting it again on WM_LBUTTONDOWN if window was already captured. I have stumbled upon the app in which edit control process WM_LBUTTONDOWN twice on one mouse click. While in windows it causes no problem, wine edit does not release capture, so other buttons inside this app become unclickable. It happens because when WM_LBUTTONDOWN is processed twice, WM_CAPTURECHANGED is sent and bCaptureState is set to FALSE, then EDIT_WM_LButtonUp does not release capture because bCaptureState is already FALSE. Thing about tests: I have added test case for this problem to be visible. I also had to use todo_wine because SendMessageA for WM_LBUTTONDOWN and WM_LBUTTONUP returns 0 in wine and 1 in windows (which is not the case for combobox test, where SendMessageА for WM_LBUTTONDOWN also returns 1 in wine). -- v4: comctl32_v6/edit: set bCaptureState flag after SetCapture() user32/edit: set bCaptureState flag after SetCapture() comctl32/tests/edit.c: Test WM_LBUTTONDOWN processing user32/tests/edit.c: Test WM_LBUTTONDOWN processing https://gitlab.winehq.org/wine/wine/-/merge_requests/10104
