C++ (Cpp) scroll_region Examples

Example #1

File: vterm_action.cpp Project: Dalrik/fbterm

void VTerm::lf()
{
	if (cursor_y < scroll_bot) move_cursor(cursor_x, cursor_y + 1);
	else scroll_region(scroll_top, scroll_bot, 1);

	if (mode_flags.crlf) cr();
}

Example #2

File: vt100.c Project: ErisBlastar/osfree

// line feed
void cursor_lf(termstate_t *term)
{
    if (term->cur_y + 1 > term->phys_h - 1)
        scroll(term);
    else if (term->cur_y >= term->scroll_bottom)
        scroll_region(term, term->scroll_top, term->scroll_bottom);
    else
        term->cur_y++;

    //vt100_redraw(term);
}

Example #3

File: vterm_action.cpp Project: Dalrik/fbterm

void VTerm::delete_line()
{
	u16 n, mx;

	n = param[0];
	if (n < 1) n = 1;

	mx = scroll_bot - cursor_y + 1;

	if (n >= mx) clear_area(0, cursor_y, width - 1, scroll_bot);
	else scroll_region(cursor_y, scroll_bot, n);
}

Example #4

File: actions.cpp Project: jeremysalwen/ChameleonIDE-Linux

void GTerm::index_up()
{
    if (cursor_y>scroll_top)
    {
        move_cursor(cursor_x, cursor_y - 1);
    }
    else
    {
        scroll_region(scroll_top, scroll_bot, -1);

		tm.Scroll(1, true);
    }
}

Example #5

File: actions.cpp Project: jeremysalwen/ChameleonIDE-Linux

void GTerm::lf()
{
    if (cursor_y<scroll_bot)
    {
        move_cursor(cursor_x, cursor_y + 1);
    }
    else
    {
        scroll_region(scroll_top, scroll_bot, 1);


    }

	tm.CursorDown();
}

Example #6

File: actions.cpp Project: jeremysalwen/ChameleonIDE-Linux

void GTerm::insert_line()
{
    int n, mx;

    n = param[0];

    if (n<1)
        n = 1;

    mx = scroll_bot - cursor_y + 1;

    if (n>=mx)
    {
        clear_area(0, cursor_y, width - 1, scroll_bot);
    }
    else
    {
        scroll_region(cursor_y, scroll_bot, -n);
    }
}

Example #7

File: vt100.c Project: ErisBlastar/osfree

// move cursor to next line
void cursor_nl(termstate_t *term)
{
    // move to start of line, if we are in carriage return
    // mode, move one line down else
    if (term->newline)
        term->cur_x = 0;
    else // care for cursor out of bounds
    {
        if (term->cur_x >= term->w - 1)
            term->cur_x = term->w - 1;
    }

    // if our new cursor position exceeds phys_h we scroll the whole terminal
    // for that the lost line is stored in the history
    if (term->cur_y + 1 > term->phys_h - 1)
        scroll(term);
    // else check if we hit the bottom of a scrolling region
    else if (term->cur_y > term->scroll_bottom - 1)
        scroll_region(term, term->scroll_top, term->scroll_bottom);
    else
        term->cur_y++;
}

Example #8

void VTerm::index_up()
{
	if (cursor_y > scroll_top) move_cursor(cursor_x, cursor_y - 1);
	else scroll_region(scroll_top, scroll_bot, -1);
}
