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 Apache 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:
    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.

FUi_Resource*Config.cpp analysis

Below is the content of FUi_ResourceProgressConfig.cpp file.

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/720×1280 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 720×1280 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/720×1280 [gitorious.org]
  2. Images are copied from qtquickcontrols-tizen/src/images/sources/720×1280 [gitorious.org] to qtquickcontrols-tizen/src/images/sources/720×1280-normalizedNames [gitorious.org]
  3. Images in qtquickcontrols-tizen/src/images/sources/720×1280-normalizedNames [gitorious.org] are normalized:
    1. Normalization script [gitorious.org] 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 [developer.android.com] It also modifies png’s with 9patch2sci [gitorious.org] tool.
    2. Best suitable files are found and exported to JS object with findProperImages.sh [gitorious.org] 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/720×1280-normalizedNames [gitorious.org] to qtquickcontrols-tizen/src/images/720×1280 [gitorious.org]
  5. Output of findProperImages.sh [gitorious.org] is JS object and is saved in DefaultSettings.js [gitorious.org] file.
  6. Colors theme JS object is generated with generateColorsObject.sh [gitorious.org] and saved to DefaultSettings.js [gitorious.org] file.
