PySDL2 example: pressing Enter inserts newlines instead of submitting the form #703
Description
When running examples/pysdl2.py, pressing Enter in Google’s search input inserts a newline instead of submitting the search. Repeated Enter presses keep expanding the input field, as shown in the attached screenshot.
Proabable cause: the example’s handle_key_event() sends KEYEVENT_CHAR for Enter but does not send KEYEVENT_RAWKEYDOWN. This may prevent web pages from handling Enter as a key press.

Could you review this isolated fix for Enter in the PySDL2 example? Commit c490d1e
Branch diff
It sends
KEYEVENT_RAWKEYDOWNbefore the existingKEYEVENT_CHAR, allowing Google’s Enter handler to submit the search and prevent a newline.I tested the unmodified v66.1 example against Google on Windows. With CEF 66, Google serves a single-line
<input>and Enter submits. The same example with CEF 147 receives a<textarea>and inserts a newline. Adding the missing keydown restores search submission with CEF 147.If this looks good to you, I'll cherry-pick this single commit into the PR branch.

Thanks, this fixes the missing keydown for Enter. I noticed that printable keys from
SDL_TEXTINPUTare sent asKEYEVENT_CHAR, but their correspondingSDL_KEYDOWNevents are ignored. Could you also sendKEYEVENT_RAWKEYDOWNfor printable key presses, while keepingSDL_TEXTINPUTresponsible forKEYEVENT_CHAR? This would let pages receive normalkeydownevents for letters as well.
