an issue with clear buffer about termqt HOT 11 CLOSED

This is a good catch. paint_cursor doesn't check if the cursor is in the valid buffer region. I posted a quick fix #27. Would you please confirm it solves this bug?

On the other hand, I would suggest you reset the cursor position to (0, 0) after clearing the buffer to avoid the cursor position surprising you.

thanks, clear buffer now works. another issue happens when the initial command fails. i get the following:
Traceback (most recent call last):

File ~/.local/lib/python3.8/site-packages/termqt/terminal_widget.py:545 in _stdout
need_draw = self._stdout_string(string)

File ~/.local/lib/python3.8/site-packages/termqt/terminal_buffer.py:1378 in _stdout_string
self.write_at_cursor(tst_buf)

buf[pos_y][pos_x] = t

IndexError: list assignment index out of range

I also modified the last lines of start.py to test the functionality of clear_buffer. no exceptions happens but in the terminal the current dir is shown twice.

    terminal_io.stdout_callback = terminal.stdout
    terminal.stdin_callback = terminal_io.write
    terminal.resize_callback = terminal_io.resize
    terminal_io.spawn()
    terminal.clear_buffer()
    terminal_io.terminate()
    terminal_io.spawn()
    terminal.set_cursor_position(0, 0)
    terminal.clear_buffer()
    terminal.set_cursor_position(0, 0)
    sys.exit(app.exec())

Terminal looks like

Great to know!

Thanks again!

Regarding the new issue of lines being displayed twice, I would think it is an issue with the shell itself (since the shell doesn't know the buffer is cleared). I may look into it a bit more today.

Thanks, another problem is with command top. the output not shows the apps running

from termqt.

oh i realized that there is no problem with command top but the font is black similar to the background.
also is there anyway to change the background of the widget?

from termqt.

Why the foreground color is black in your case? I believe the default color is white. Can you investigate this?

from termqt.

my foreground is white. when i execute top command in the bash, the summary of my resources are shown as white, but the processes have black font color

from termqt.

it seems that the lines that get updated have black foreground color. in my case even the upper lines after a while become black as shown in the following pictures

from termqt.

I see. The issue is caused by the broken support for some escape sequences. I have pushed a new commit to #27. Would you have a look?
