View source for Qt Interface

== Introduction ==

Qt / Qt4 is the default, plain, graphical, [[interface]] to VLC, made using the [http://www.trolltech.org/qt Qt] library (linux users may need to have this installed). It is used as the default interface on the [[Windows]] and [[Linux]] versions of {{VLC}} from version 0.9.0 and up.


Unless you change the [[preferences]], {{VLC}} > 0.9.0 will start up in the Qt4 interface, but you can force this by running
 vlc '''-I qt'''
or
 qvlc


If Qt4 is not avaliable, it will probably revert to using the [[Console|rc]] (console) interface, even if you force it. The most likely reason for this is if Qt4 hasn't been installed, or if it wasn't linked in (using the ./configure). See [[compiling VLC]] [http://developers.videolan.org/vlc/] for information on compiling.

=== Status Bar ===

The Status Bar has three distinctive portions displaying information.
* Name label
* Speed label
* Time label

Here are the actions you can do on the status bar:

{| class="wikitable" style="text-align:center" 
!
! Select !! Left Click !! Right Click !! Middle Click !! Double Click
|- 
! Name label
|| Prepare for copy || Give focus for arrows selection || Copy menu || - || Word selection 
|-
! Speed label
|| - || - || Show fine rate speed adjusting || - || reset to normal 1.00x speed 
|-
! Time label
|| - || Switch remaining/elasped time || Switch remaining/elasped time || Switch remaining/elasped time || Open the "Go To Time" dialog
 
|}

==== Time label ====
The timeLabel shows mm:ss/nn:tt in the statusBar. 

If the time is longer that one hour, it shows hh:mm:ss/ii:nn:tt.

If you click on it, it shows remaining time instead of elapsed time.
If you double click on it, it opens the open the GOTOTime dialog in order to skip easily.

If vlc doesn't know the total time, like in avi/http, it shows the elapsed time only, and --:-- instead of total time.

=== System Tray Icon ===

=== Controller ===


==== Main Slider ====

The main slider does control the timeline.

When you click somewhere on the timeline, it skips the movie to that place.
When you drag the slider of the timeline, it follows the position on the movie.

When you hover it with your mouse, it shows you where it would go if you click.


==== Sound Slider ====

The sound slider does control the volume.

When you click somewhere on the soundSlider, it changes the volume.
When you click and drag on the soundSlider, it changes the volume too. If you release the click really outside of the volume slider, it will reset to your old value

When you hover it with your mouse, it shows you the volume it would be if you click it.

==== Sound range ====
The sound goes from 0% to 200% and can go up to 400%

100% means normal output of the file without amplification.
Above 100% means that it may use software amplification, and it could distort sound (it usually doesn't, but it could).
