#4932 has been merged now, so this needs a rebase.

JingMatrix · 2022-03-31T08:34:26Z

I apply this PR with the current HEAD.
The api of wlr_output_layout_get_box has changed, so you should change your code a bit in sway/sway/input/text_input.c.
After this, I compiled your code, and tested it with alacritty and kitty, both gave me the same result:
the popup showed up at the very beginning, and then never showed up again.

dragove · 2022-04-05T15:50:09Z

I've tested it with AUR package sway-im with fcitx5 as input method in kitty. When the character meets the end of a line, the popup will be hidden. I don't know if it is a issue with kitty. Alacritty won't meet this issue since it won't put characters into the line before I select my needed word in IM.
Edit: This problem only shows up when I set default_border none 0 in sway configuration file.

JingMatrix · 2022-04-07T20:44:25Z

Now I test it ( after fixing the output_box api problem) with the HEAD of fcitx5 and HEAD of sway, everything works!

@emersion Looks like this is ready for another review :)

sway/tree/container.c

 			wlr_subsurface_from_wlr_surface(surface);
 		surface = subsurface->parent;
 	}
+	if (wlr_surface_is_input_popup_surface_v2(surface))


Style: braces are mandatory

emersion · 2022-05-11T14:12:37Z

sway/input/cursor.c

 		return NULL;
 	}

+	if ((*surface = input_popup_surface_at(output,


We should probably move this up right before "check for unmanaged views" to allow fullscreen surfaces to work with IMEs.

emersion · 2022-05-11T14:14:36Z

sway/input/cursor.c

+			continue;
+		}
+		double _sx = ox - lx;
+		double _sy = oy - ly;


This mixes up layout-local coords and output-local coords. I think input_popup_surface_at should take layout-local coords instead.

emersion · 2022-05-11T14:18:51Z

sway/input/text_input.c

+	wl_signal_add(&view->events.unmap, &popup->focused_surface_unmap);
+
+	// Since the focus has changed, the popup may have to adjust
+update_popup:


Instead of a goto, else if/else would be more readable.

emersion · 2022-05-11T14:22:07Z

sway/input/text_input.c

+
+	struct sway_view *view = view_from_wlr_surface(
+		text_input->input->focused_surface);
+	if (view->container == NULL) {


This can return NULL here.

This logic doesn't work on subsurfaces nor xdg_popups.

@tadeokondrak @emersion This PR seems to have some amendments pending. Can I take over by starting another PR?

Someone has been testing this with SDL and it seems there's an issue with fcitx, but only when integer scaling is used...?

libsdl-org/SDL#5892

We have some ideas on our end, but figured we'd include the issue here in case it's something obvious on the compositor side of things.

tadeokondrak · 2022-11-23T11:42:08Z

Sorry about this PR... I've left it open because I thought I could get to it eventually - but it looks like someone else is continuing the effort at #7226, which is great.

Thanks that you have return back..Your help is still needed..Do you still have time now?

This mixes up layout-local coords and output-local coords. I think input_popup_surface_at should take layout-local coords instead.

I do not know how to make change about this request, can you help me?
