From 2132c063af3adf1d612359e0ed42c7cbd8b4290c Mon Sep 17 00:00:00 2001 From: andrew-pa Date: Thu, 10 Jun 2021 20:07:52 -0700 Subject: backport: fix(windowing): positioning of relative floats Fix relative floating windows so that they open in the correct position relative to each other. Also make sure that their positions are correct immediately after creation without a redraw. --- src/nvim/window.c | 34 +++++++++- test/functional/ui/float_spec.lua | 126 ++++++++++++++++++++++++++++++++++++++ 2 files changed, 159 insertions(+), 1 deletion(-) diff --git a/src/nvim/window.c b/src/nvim/window.c index 472a52e113..a64dee24a0 100644 --- a/src/nvim/window.c +++ b/src/nvim/window.c @@ -737,6 +737,37 @@ void win_config_float(win_T *wp, FloatConfig fconfig) redraw_later(wp, NOT_VALID); } + // compute initial position + if (wp->w_float_config.relative == kFloatRelativeWindow) { + int row = wp->w_float_config.row; + int col = wp->w_float_config.col; + Error dummy = ERROR_INIT; + win_T *parent = find_window_by_handle(wp->w_float_config.window, &dummy); + if (parent) { + row += parent->w_winrow; + col += parent->w_wincol; + ScreenGrid *grid = &parent->w_grid; + int row_off = 0, col_off = 0; + screen_adjust_grid(&grid, &row_off, &col_off); + row += row_off; + col += col_off; + } + api_clear_error(&dummy); + if (wp->w_float_config.bufpos.lnum >= 0) { + pos_T pos = { wp->w_float_config.bufpos.lnum + 1, + wp->w_float_config.bufpos.col, 0 }; + int trow, tcol, tcolc, tcole; + textpos2screenpos(wp, &pos, &trow, &tcol, &tcolc, &tcole, true); + row += trow - 1; + col += tcol - 1; + } + wp->w_winrow = row; + wp->w_wincol = col; + } else { + wp->w_winrow = fconfig.row; + wp->w_wincol = fconfig.col; + } + // changing border style while keeping border only requires redrawing border if (fconfig.border) { wp->w_redr_border = true; @@ -770,7 +801,6 @@ int win_fdccol_count(win_T *wp) } } - void ui_ext_win_position(win_T *wp) { if (!wp->w_floating) { @@ -817,6 +847,8 @@ void ui_ext_win_position(win_T *wp) int comp_row = (int)row - (south ? wp->w_height : 0); int comp_col = (int)col - (east ? wp->w_width : 0); + comp_row += grid->comp_row; + comp_col += grid->comp_col; comp_row = MAX(MIN(comp_row, Rows-wp->w_height_outer-1), 0); comp_col = MAX(MIN(comp_col, Columns-wp->w_width_outer), 0); wp->w_winrow = comp_row; diff --git a/test/functional/ui/float_spec.lua b/test/functional/ui/float_spec.lua index 51ee922d23..1457c62b54 100644 --- a/test/functional/ui/float_spec.lua +++ b/test/functional/ui/float_spec.lua @@ -152,6 +152,132 @@ describe('float window', function() eq(10, width) end) + it('opened with correct position', function() + local pos = exec_lua([[ + local bufnr = vim.api.nvim_create_buf(false, true) + + local opts = { + width = 10, + height = 10, + col = 7, + row = 9, + relative = 'editor', + style = 'minimal' + } + + local win_id = vim.api.nvim_open_win(bufnr, false, opts) + + return vim.api.nvim_win_get_position(win_id) + ]]) + + eq(9, pos[1]) + eq(7, pos[2]) + end) + + it('opened with correct position relative to the cursor', function() + local pos = exec_lua([[ + local bufnr = vim.api.nvim_create_buf(false, true) + + local opts = { + width = 10, + height = 10, + col = 7, + row = 9, + relative = 'cursor', + style = 'minimal' + } + + local win_id = vim.api.nvim_open_win(bufnr, false, opts) + + return vim.api.nvim_win_get_position(win_id) + ]]) + + eq(9, pos[1]) + eq(7, pos[2]) + end) + + it('opened with correct position relative to another window', function() + local pos = exec_lua([[ + local bufnr = vim.api.nvim_create_buf(false, true) + + local par_opts = { + width = 50, + height = 50, + col = 7, + row = 9, + relative = 'editor', + style = 'minimal' + } + + local par_win_id = vim.api.nvim_open_win(bufnr, false, par_opts) + + local opts = { + width = 10, + height = 10, + col = 7, + row = 9, + relative = 'win', + style = 'minimal', + win = par_win_id + } + + local win_id = vim.api.nvim_open_win(bufnr, false, opts) + + return vim.api.nvim_win_get_position(win_id) + ]]) + + eq(18, pos[1]) + eq(14, pos[2]) + end) + + + it('opened with correct position relative to another relative window', function() + local pos = exec_lua([[ + local bufnr = vim.api.nvim_create_buf(false, true) + + local root_opts = { + width = 50, + height = 50, + col = 7, + row = 9, + relative = 'editor', + style = 'minimal' + } + + local root_win_id = vim.api.nvim_open_win(bufnr, false, root_opts) + + local par_opts = { + width = 20, + height = 20, + col = 2, + row = 3, + relative = 'win', + win = root_win_id, + style = 'minimal' + } + + local par_win_id = vim.api.nvim_open_win(bufnr, false, par_opts) + + local opts = { + width = 10, + height = 10, + col = 3, + row = 2, + relative = 'win', + win = par_win_id, + style = 'minimal' + } + + local win_id = vim.api.nvim_open_win(bufnr, false, opts) + + return vim.api.nvim_win_get_position(win_id) + ]]) + + eq(14, pos[1]) + eq(12, pos[2]) + end) + + local function with_ext_multigrid(multigrid) local screen before_each(function() -- cgit
