 # View
 
 ![Development status](doc/status-gamma.svg)
 
 Client, GUI application, which allows one to run CuteHMI project in a window.
 
 By default this tool shows only a simple help screen.

 CuteHMI approach is to treat each project as a first-class QML extension, so the purpose of the tool is to load specified extension
 and display one of its QML components. Any extension that provides graphical UI QML component can be loaded as *cutehmi.view.4*
 project. Use command line argument to specify an extension.
 
 For example to run [Simple View](../../extensions/CuteHMI/Examples/SimpleView.2/) example use following command.
 ```
 cutehmi.view.4 CuteHMI.Examples.SimpleView.2
 ```
 
 To run project from QtCreator click `Projects` -> `Run`. Select `cutehmi.view.4` from `Run configuration`. In the
 `Command line arguments` box type: `CuteHMI.Examples.SimpleView.2`.
 The window should look similar to the screenshot below.

 Default loader picks `View` as default QML component to load. Component can be specified with second positional argument. For
 example following displays `RectangularElement` component from the previous example.
 ```
 cutehmi.view.4 CuteHMI.Examples.SimpleView.2 RectangularElement
 ```
 
 One can also use `--init` option to replace default loader with custom one.
 
 You can use `--help` command line argument to see a list of all possible command line options.
 
 For debug builds use `cutehmi.view.4.debug` instead of `cutehmi.view.4`.
 
 ## Providing Qt Quick Controls configuration file
 
 Qt allows for configuring the style of application with a special `qtquickcontrols2.conf` file. This file has to be built into
 application resources. Extension may provide it within `cutehmi.view.rcc` resource file, which shall be intalled into extension
 dedicated directory. For this `cutehmi.rcc` Qbs module can be used, which generates `rcc` artifacts from `qrc` files. Extension just
 needs to put `qtquickcontrols2.conf` (root prefix) inside `cutehmi.view.qrc`, declare dependency on `cutehmi.rcc` module and assign
 `cutehmi.qrc` tag to the `cutehmi.view.qrc` file (module `cutehmi.rcc` uses distinct tag to prevent `Qt.core` from creating `cpp`
 files with `qrc` resources, which is not desired for simple QML extensions).
 
 ```
 Depends { name: "cutehmi.rcc" }
 
 Group {
     files: "cutehmi.view.qrc"
     fileTags: "cutehmi.qrc"
 }
 ```
 
 Resource file can be also specified with `--resource` option.
 
 ## Changes
 
 Compared to previous major version following changes were made.
 - View looks for `View` component instead of `Main`.
 - Extension is specified with first positional argument instead of `--extension` argument.
 - Component is specified with second positional argument instead of `--component` argument.
 - It is possible to register resource on startup (by the extension with `cutehmi.view.rcc` lookup or by the user with `--resource`
   argument).
