Shortcut ubuntu 16.4.1 QT5 [Ctrl][x]

[Jan Gruuthuse]

On Ubuntu 16.04.1 LTS QT5 avidemux 2.6.12 does not have working/show keyboard short cuts. This becomes an productivity issue.
Ctrl+X or Ctrl+Z or Ctrl+C or Ctrl+V
On Ubuntu 14.04.4 LTS these short cuts are showing and working
Was reported before: QT5 ubuntu 16.04 keyboard shortcuts
Could you please look in to this matter?

I suspect a missing library or a condition in source why that code is not build/working?
Is the program detecting the localisation of the keyboard and posing a conflict with the system language?

build on basis of: Compiling Avidemux 2.6.x
with added: avidemux 2.6.12 Compiling Avidemux on Ubuntu 16.04.1 LTS

FYI: On Fedora 24, the keyboard shortcuts are displayed in the menus correctly in a Qt5 build from the current git, but only few work correctly. E.g. Ctrl+V after Ctrl+X has no effect except of printing

Code Select Expand

  [pasteFromClipBoard]  Pasting from clipboard to [...]

in the terminal. "[" and "]" don't work too, but setting the markers work when selected from the menu via keyboard (I should check whether this work in a Qt4 build...).

>8>8 .... >8>8

Ubuntu 16.04.1 includes Qt 5.5.1, Ubuntu 14.04.4 Qt 5.2.1. Fedora 24 packages Qt 5.6.1.

Meanwhile I was testing a qt4 build from the git and found that "[" and "]" work fine there. Pasting seems to be a special item and sort of broken like in the qt5 build.

going over my install:

System Settings
System Language support:
Keyboard input method system: [IBus]

[Jan Gruuthuse]

by the way in Terminal this comes along:

Paint event:
QWidget::paintEngine: Should no longer be called

[eumagga0x2a]

If I switch the input method to í•Å"ê¸â,¬ (Hangeul) all the keyboard shortcuts that worked with the keyboard set e.g. to German still work. This is with libinput 1.4.0, ibus 1.5.13 and gnome-shell 3.20.3.

I get the same warnings about QWidget::paintEngine too.

My Qt5/16.04 versions looks like your Qt4 version
Are you running gnome ?

[Jan Gruuthuse]

no, unity

Do other Qt5 applications like qtcreator show the same problem? Do you have appmenu-qt5 installed? The bug https://bugs.launchpad.net/ubuntu/+source/ipe/+bug/1582329 could be related then.

[Jan Gruuthuse]

both are installed:

Is this of any help:

removing  appmenu-qt5 has partial shortcuts
Working: Ctrl+X or Ctrl+Z or Ctrl+C or Ctrl+V

Fine, the means the buggy appmenu-qt5 was the culprit.

(Off topic: Ctrl+V shortcut works, but the underlying function doesn't work right, IMHO.)

Not working: [Alt gr] [ [ ] and [Alt gr] [ ] ]

The same on Fedora with avidemux3_qt5. This could be an Avidemux bug then.

I would not say a bug, rather some QT implementation change.

The following patch fixes not working square brackets as keyboard shortcuts for "Set marker A" and "Set marker B" for me:

}

Indeed, the UI does not match the shortcut
Probably will change it to Page UP/Down to go and CTRL+page up/down to Set
The [] are a pain depending on the keyboard
