window: message dialog not in foreground when launched from a window-less process

[benma]

Hi

This is exactly the crate I needed to prompt the user with a message. However, my process on runs in the background without a main window.

On Windows, the dialog appears in the background (behind other open windows like browser, etc.). It is visible in the task bar, but the user is not going to notice this easily. Is there a way to open the dialog in the foreground, or to add support for this somehow?

As a test, I added MB_SYSTEMMODAL to the flags here:

rfd/src/backend/win_cid/message_dialog.rs

Line 65 in 6f9062e

flags: level | buttons,

which fixed the issue.

Would you be open for a PR that extends the API to allow setting this flag?

Sure, I would probably just make it the default and call it a day

Making it default may have undesired consequences:

Same as MB_APPLMODAL except that the message box has the WS_EX_TOPMOST style.
Use system-modal message boxes to notify the user of serious, potentially damaging errors that require immediate
attention (for example, running out of memory).
This flag has no effect on the user's ability to interact with windows other than those associated with hWnd.
