Convert UI to use libmythui.

[Isaac Richards]

The frontend and plugins need to be rewritten to use MythUI.

[GreyFoxx]

One nice feature would be the ability to have a text area scroll from right to left when selected. For Example if you are scrolling through a tree list of filenames, and the name is larger than the display area have it scroll after a moment of being highlighted allowing us to see the full content. The amount of time to wait before scrolling starts could be configurable.

[anonymous]

It would be nice to be able to have exact x/y+wxh control over where each button in a buttongroup/menu is located on the screen.

For example if I only want a visiblerowlimit of 5 items, but I want to define the exact location information for each of the 5 "rows".

This would allow it to be very flexible when aligning to elements from a image/background/layer.

[Isaac Richards]

(In [9156]) Things now use libmythui for the main window. Nothing is actually drawn with mythui yet.

Remove MythMainWindow? from libmyth. Update the MythMainWindow? class in libmythui for the changes since it was started. Rename/move a few files/classes in libmythui so they don't conflict with libmyth for now.

Note the install location for the headers changed (from <prefix>/mythui to <prefix>/mythtv/libmythui). You may want to delete the old installed headers.

A distclean may be needed to compile everything.

Refs #12.

[Isaac Richards]

(In [9254]) The menu is now drawn by mythui. Random stuff might be broken. This will be slow (for now) for people without working hardware opengl accel. Still compatible with existing themes, though that probably won't last long.

Details, other than the obvious:

• Hash strings in the opengl painter with their font style.
• Make jumppoints work with mythui windows.
• Added some more compatability code to mythui to handle the old UI stuff.
• The themedmenu class still needs to broken out more into separate components.

Refs #12.

[mythdev@…]

Not sure if you are already want feedback in this very early stage of development, but I experienced the following.

On my epia box, using the OpenGL from the open via driver, the background of my menu is white. The rest of the pictures are OK and the fade-in/fade-out of the menu works perfectly and looks really, really great! Maybe my experience can help you?

[joshebel@…]

My Intel i810/815 videocard in 16 bit 800x600 using Xorg GLX takes 10-15 seconds to fade in or out. The CPU is 100% in mythfrontend during menu changes. It would be wonderful to have a configure option to disable opengl eye candy on the builds.

[florinbaiduc@…]

Perhaps you already noticed this but... The arrows are not getting detected by the screen->GetChildAt?(p) call in MythMainWindow?. This is strange, because they are declared as chidren of a MythScreenType?, and being a MythUIStateType they already have the area and position declared within a MainWindow?.

[Isaac Richards]

(In [9561]) First step of making the menu not manually draw itself. Qt painting should be faster, now, as it no longer redraws the entire screen every update.

Refs #12.

[anonymous]

you probably didn't want to know this yet -

the backwards compatibility mode now seems broken

• ie when USeOpenGLPainter is set as 0 the menu entries cannot be seen - still work - you just have to have a good memory. :)

[mythdev@…]

I also saw this problem with the Retro theme. The MythCenter? theme works fine. So it has something to do with specific themes. Tested it with the UseOpenGLPainter=0

[Isaac Richards]

(In [9644]) Got enough feedback on where the opengl stuff works/doesn't. Removed the temporary UseOpenGLPainter override. Added new setting to the Appearance page to select which painter to use, and default it back to Qt.

Refs #12.

[awk@…]

It would appear that you can't 'mix n match' the QWidget and QGLWidget code on Mac OS X. If you insantiate a QGLWidget (or subclass) you need to use the QGLPainter, a QPainter will not draw correctly to the screen. Given the Mac OS X OpenGL architecture this isn't surprising. Is the 'grand plan' here to remove the QPainter approach entirely in the future ? Or to leave it in place for those systems without sufficient OpenGL performance ?

If the plan is to allow both changes I think MythMainWindow? will need some refactoring and changes in inheritance so that either there are two subclasses one for GL one for non-GL or an alternative approach with a single MythMainWindow? with a private class member to handle the different widgets. I'm happy to help with the work if I can - but I think this is probably beyond the realm of a straightforward patch 8-)

[Isaac Richards]

(In [9949]) Finally have a new XML parsing framework for mythui that I'm happy with. Mostly checking in so I don't change my mind again.

On a per widget type basis, parsing is significantly simpler than the old UI code, no more redundant code.

New framework allows for widget trees to be pre-defined, and then have specific overrides when actually used. This will allow defining something like the selection tree in the 'watch recordings' screen once, and using it with a single line of code in other screens (ie., mythmusic, game, video, etc all currently redefine that exact same widget in each .xml file). Should lead to much smaller/easier to create/customize themes, as well as more consistant feel over the entire theme.

Tnis isn't live or even hooked up to anything yet. Only have fonts/images/text types done so far.

Refs #12.

[Isaac Richards]

(In [9956]) Flesh out the rest of the UI types for parsing/inheriting, and make it all actually work.

Refs #12.

[Isaac Richards]

(In [9959]) Themes can now define a 'backgroundwindow' element that are more complex than just a single image, and will be present on all screens using mythui. See GANT for an example.

Other changes: fix theme reloading, close small font memory leak, allow images to request to be full-screen, themes can override stuff in base.xml if so desired, add alpha/pulse controls to the generic item type..

Refs #12.

Please don't make changes to tickets anonymously for no good reason.

[daniel at file-factor dot de]

Did you ever consider porting this to Qt4?
Qt4 has a new painting framework called ​Arthur which has a software rendering backend and an opengl backend. You would get the opengl acceleration "for free".
Since version 4.2 Qt also has great support for SVG and has a native ​SVG renderer which allows to load SVGs (or parts of them) and render them into a QWidget or QPixmap.

Perhaps this would be a good way to save some development-time and get nice new possibilities.

Sorry, my mail adress was wrong.

(In [14944]) Refs #12. Splits non-settings out of settings.h.

Settings, setting groups, setting dialogs, and setting storage clases are split out into separate headers and cpp's in this patch. settings.h still includes all of them to minimize disruptions to other files.

This is basically so I can start working on porting MythTV settings to mythui while keeping the includes clean of Qt widget headers. this doesn't require recompiling any plugins or relinking any of MythTV because the classes themselves are unchanged.

(In [17123]) Adds an image reflection effect to MythUI. This is more proof of concept than the final implementation, I'll be optimising and tweaking it.

See ​http://miffteevee.co.uk/imagebin/mythui_imagereflection3.png for examples of reflection effects.

The following element belonging to <imagetype> defines the look

<reflection axis="vertical" shear="50" scale="50" length="50" />

Axis - the reflection axis {vertical,horizontal} Shear - Percentage shear of the reflection shear, affects the angle of the reflection Scale - Percentage to scale down the reflection, affects the angle between the image and the 'surface' Length - Percentage of image to retain in the reflection, affects the length of the reflection

Image transformations will be added shortly as well, allowing images to be sheared, rotated etc

N.B. It's not really intended that it be used for static theme images, reflection effects for those images would be better 'hardcoded' using your favourite graphics editor. This is intended to be used with dynamic content, album art, movie posters, preview images and gallery images.

(In [17174]) Adds what I'm calling 'Centre Hold' scrolling to mythlistbutton. This is where the selected item remains static in the centre of the visible list area and the list items move instead. The behaviour is similar to that of the category list in "Watch Recordings".

Adds a new element to the listbutton, <scrollstyle> which accepts values of "free", the current behaviour and "center", the new behaviour. The intention is to allow further styles to be added later.

This was tested with the vertical layout and the horizontal layout should work too, but it doesn't yet work with the grid layout and fixing that isn't a high priority at the moment. There are several reasons for adding this option now, but the one which will interest most people is to take us one step closer to a "cover flow" effect.

[stuartm]

(In [17287]) Adds a spinbox widget to mythui. This is a functional placeholder until I get the time to write a more efficient version. Like the final version this inherits from mythlistbutton and adds the ability to specify an arbitrary range of numerical values, unlike the final version if you define 100 possible values then 100 items are put into the list instead of determining the next/prev values only when they are needed.
