Let's make a button by floating window!
I made a button using floating window. You can push the button by ENTER.
How do I make it look like a button?
- Prepare two windows, front and back.
- Make the color of the back a little darker than the color of the front.
- Lower the position of the front so that it covers the back when it is pressed.
When ENTER is pressed, just move it back down and it will appear to be pressed.
Code
let g:button_window = {} hi FrontColor guibg=#F27200 hi BackColor guibg=#AC5D24 function! s:center(str) let width = nvim_win_get_width(0) let shift = floor(width/2) - floor(strdisplaywidth(a:str)/2) return repeat(' ', float2nr(shift)) . a:str endfunction function! s:remove_button() abort let front_win = nvim_get_current_win() let back_win = g:button_window[front_win] call nvim_win_close(back_win, v:true) call nvim_win_close(front_win, v:true) call remove(g:button_window, front_win) endfunction function! s:create_window(config, ...) abort let hi_group = a:1 let transparency = get(a:, '2', 0) let buf = nvim_create_buf(v:false, v:true) let win = nvim_open_win(buf, v:true, a:config) if hi_group != '' call nvim_win_set_option(win, 'winhighlight', hi_group) call nvim_win_set_option(win, 'winblend', transparency) call nvim_win_set_config(win, a:config) endif return win endfunction function! s:push() abort let front_win = nvim_get_current_win() let back_win = g:button_window[front_win] let config = nvim_win_get_config(front_win) let config.row += 1 call nvim_win_set_config(front_win, config) sleep 100ms redraw let config.row -= 1 call nvim_win_set_config(front_win, config) endfunction function! s:main() abort let row = 20 let col = 20 let width = 20 let height = 3 let config = { 'relative': 'editor', 'row': row, 'col': col, 'width': width, 'height': height, 'anchor': 'NW', 'style': 'minimal' } " back window let back_config = deepcopy(config) let back_config.row += 1 let back_win = s:create_window(back_config, 'Normal:BackColor') " front window let front_win = s:create_window(config, 'Normal:FrontColor') call setline(2, s:center('Button')) call cursor(2, 0) nnoremap <buffer><nowait><silent> :q :call <SID>remove_button() nnoremap <CR> :call <SID>push()<CR> let g:button_window[front_win] = back_win endfunction call s:main() Bonus: Fire bullets with ENTER
And you can move by hjkl.
