If more text is added to a textbox than fits into the window, the last
lines are stripped. In BOTTOM (and non-SCROLL) mode, it makes more sense
to strip the first lines. This is used by shellwindow, e.g. in package
management menu.
This runs an external command inside a pty. Running inside a pty,
external commands using stdio(3) will disable stdout buffering when
running from a terminal, which is often desirable.
opkg has several problems with complex system updates, especially when
having to update itself and with the package ordering during update
To avoid hard coding the workarounds into neutrino, just call a script
named "system-update" (if available) instead of "opkg upgrade".
This script can be tuned to the specific target and its problems.
When no scrollbar is present, just pass through up/down keys instead
of only canceling the hintbox. This restores the behaviour before
commit dde298b1b7.
Prominent examle is the "channel not available" popup which prevented
further channel switching until canceled.
RC_up and RC_down are used for text scroll, but most message texts
are small and no scroll mode is required. In case of large texts
it should falling back to scroll mode.
After increased clock height settings, position of infoclock was wrong.
Old font instance and old width were not changed related to new instance.
TODO: It works but procedure with helper class seems is rather elaborate
and should be thoroughly revised.
I recommend callbacks via native type save signal/slot handler.
Default button font type in footer is button text type and not footer font.
Faces of buttons are still disabled and not visible here,
therefore this should be ok at the moment.
Different font types could have different glyph heights,
Therfore static values seems not really senseful.
eg. chars like ÄÁÂÅÈÉÊËÌÍÎÏÑÒÓÕÖÙÛÜÝ could paint over defined height,
Note: However, depending of implementations, the font image may change.
Most likely this must be adapted to some parts.
Default fonts for header and footer must be handled too.
After font settings changes these objects could be invalid.
Default fonts have invalid pointers after font changes too. Extra reset is required.
