Qt for Tizen: Qt Quick Controls - Development

Current Status

Following table show current status of porting Tizen Controls to Qt Quick cross platform controls. Not all Tizen controls will be ported - sometimes equivalent component already exists in Qt (e.g. Animations). Some of them need deeper analysis and integration with platform (Search, Keypad) and they will be considered later. Possible States:
* ? - not reviewed
* Analysed - we know what to do to port certain control
* In Progress
* Done - ported

Assumptions

• Qt quick controls for Tizen should be derived from qtquickcontrols. This may be opportunity of merging Qt Quick Controls for Tizen with Qt Quick Controls in the future.
• The controls should have Tizen look and feel based on Tizen UI Controls (see UiControls sample app from Tizen SDK available at https://developer.tizen.org/documentation/dev-guide under Tizen Native App Programming->Sample applications->UiControls)

• All content of the OSP libraries is licensed under the [license] so images can be reused

Main conclusions after analysis of Tizen 2.1b controls

General

• Controls are placed in libosp-uifw library. Sources could be obtained from download.tizen.org. For emulator it could be http://download.tizen.org/snapshots/2.1-emul/common/latest/repos/tizen-main/source/ (osp-uifw-.rpm package)
  The package can be unpacked by this command:
  

  <br />rpm2cpio myrpmfile.rpm | cpio <s>idmv<br />
  

  
  It provides osp-uifw sources.
  * Each control contains information about related resources hardcoded in FUi_ResourceControlConfig.cpp. For example FUi_ResourceProgressConfig.cpp lists resources for FUiCtrlProgress.

h3. FUi_Resource*Config.cpp analysis
Below is the content of FUi_ResourceProgressConfig.cpp file.

<br />#include &quot;FUi_ResourceProgressConfig.h&amp;quot;
<br />START_UI_CONFIG(PROGRESS);<br />{<br /> ADD_COLOR_CONFIG(BAR_BG_NORMAL, $W062L1);<br /> ADD_COLOR_CONFIG(BAR_NORMAL, $W062L2);
<br /> ADD_IMAGE_CONFIG(BAR_BG_NORMAL, #00_progress_bg.#.png);<br /> ADD_IMAGE_CONFIG(BAR_NORMAL, #00_progress_bar.#.png);<br /> ADD_IMAGE_CONFIG(BAR_BG_EFFECT, #00_progress_ef_bg.#.png);<br /> ADD_IMAGE_CONFIG(BAR_EFFECT, #00_progress_bar_ef.#.png);
<br /> START_UI_CONFIG_MODE(720x1280);<br /> {<br /> ADD_SHAPE_CONFIG(BAR_HEIGHT, 36);<br /> ADD_SHAPE_CONFIG(BAR_LEFT_MARGIN, 36);<br /> ADD_SHAPE_CONFIG(BAR_OFFSET, 9);
<br /> ADD_SHAPE_CONFIG(MINIMUM_WIDTH, 276);<br /> ADD_SHAPE_CONFIG(MINIMUM_HEIGHT, 36);<br /> }<br /> END_UI_CONFIG_MODE(720x1280);<br />}<br />END_UI_CONFIG(PROGRESS);<br />

Important from our point of view are ADD__CONFIG macros (defined in FUi_ResourceConfigMacro.h):
ADD_COLOR_CONFIG first argument is the key, second argument is the value but - if second value starts with $ then it acts as the key from osp-uifw-source-dir/res/common/usr/share/osp/themes xml file. The real value is related to that key. So first line in FUi_ResourceProgressConfig.cpp inserts pair (BAR_BG_NORMAL,"#FFF0EDE9") into some resource map . "#FFF0EDE9" is the value from osp-uifw-source-dir/res/common/usr/share/osp/themes/white.xml corresponding to $W062L1 key.

• ADD_IMAGE_CONFIG - sets image from ex. osp-uifw-1.2.1.0/res/common/usr/share/osp/bitmaps/720x1280 and its subdirectiories.
• ADD_SHAPE_CONFIG - self explanatory

Images used in Controls:
Tizen uses mainly Andorid like 9-patch images. Unlike QML BorderImage they contains information about bottom,top, left and right areas inside png file.

Preparing Tizen resources for Qt Quick Control for Tizen

Assumptions

• Currently only white theme will ported
• Currently only 720x1280 resolution will be supported
• Tizen 9-patch images will be modified (border information will be moved from png to sci)

Steps

1. Images are copied from osp-uifw source package to "qtquickcontrols-tizen/src/images/sources/720x1280":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/src/styles/images/source/720x1280
2. Images are copied from "qtquickcontrols-tizen/src/images/sources/720x1280":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/src/styles/images/source/720x1280 to "qtquickcontrols-tizen/src/images/sources/720x1280-normalizedNames":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/src/styles/images/source/720x1280-normalizedNames
3. Images in "qtquickcontrols-tizen/src/images/sources/720x1280-normalizedNames":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/src/styles/images/source/720x1280-normalizedNames are normalized:
   1. "Normalization script":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/blobs/master/src/styles/images/source/720x1280-normalizedNames/normalizationScript.sh is invoked. It removes ".#" from fileNames (type of QML image source is url and there is problem with loading files when file name contains #'s). These files are "nine patch images":http://developer.android.com/tools/help/draw9patch.html It also modifies png's with "9patch2sci":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/tools/9patch2sci tool.
   2. Best suitable files are found and exported to JS object with "findProperImages.sh":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/blobs/master/src/styles/images/source/720x1280-normalizedNames/findProperImages.sh script. Image files are pointed in FUi_ResourceControlConfig.cpp by name and best file path should be choosen. Alghoritm is self explanatory - see findProperImages.sh script.
4. Images are copied from "qtquickcontrols-tizen/src/images/sources/720x1280-normalizedNames":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/src/styles/images/source/720x1280-normalizedNames to "qtquickcontrols-tizen/src/images/720x1280":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/trees/master/src/styles/images/720x1280
5. Output of "findProperImages.sh":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/blobs/master/src/styles/images/source/720x1280-normalizedNames/findProperImages.sh is JS object and is saved in "DefaultSettings.js":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/blobs/master/src/styles/DefaultSettings.js file.
6. Colors theme JS object is generated with "generateColorsObject.sh":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/blobs/master/src/styles/themes/generateColorsObject.sh and saved to "DefaultSettings.js":https://gitorious.org/qt-quick-controls-for-tizen/qtquickcontrols-tizen/blobs/master/src/styles/DefaultSettings.js file.
