Specific features of the applications for Windows Phone
 Warning
From version 21, no Windows Phone project can be created anymore. Only the projects in Universal Windows 10 App mode are available.
The method for developing applications for Windows Phone differs from the method for developing applications with WINDEV Mobile in the following fields: Note: The list of available features evolves very quickly. The forthcoming version (available for download) will include the evolutions and new features. To find out the list of functions available in Windows Phone, see the Windows Phone paragraph in New features of WLanguage. Available project elements The following project elements are available for the Windows Phone development: - Windows.
- Sets of procedures.
- Window templates.
The following project elements are not available for the Windows Phone development: - Queries
- Components.
- Classes.
- Reports and report templates.
- Control templates.
- Internal windows.
Available controls The following controls are available for the Windows Phone development: - Button.
By default, the buttons use the system skin template. To get custom buttons (buttons with an image for example), we recommend that you use a clickable image. - Image.
The image formats supported in Windows Phone are PNG and JPEG. - Check Box
- Static
- Edit control
- Radio Button
- Looper
Note: The loopers are used to replace the tables in a Windows Phone application. Indeed, the concept of table does not exist in Windows Phone and in Android. The tables are not used in Windows Phone for the following reasons:: - The interface of tables is not appropriate.
- Problem regarding the space in the windows: the columns and the column headers would not be displayed.
- The row height would be too small to interact with it by touch.
- The tables are not used in the interface standard of this system.
Note: The properties of control borders, although available in edit, are not supported by the Windows Phone applications in this version. Windows Phone does not support the database systems. However, you have the ability to handle the files (text or binary files) containing data (fXXX functions). Stored on the phone. You can for example retrieve data via the HTTP functions ( HTTPRequest, HTTPGetResult, ...) and save it locally in a file found on the phone. Modal windows The modal widows are not supported by the Windows Phone operating system. Open is not allowed. The windows can be opened by OpenChild. When it is closed, a child window can call a local procedure of the window that opened it in order to pass a return value to it. A return value can also be returned via a global variable. Skin template The Windows Phone applications use the "ActivPhone7" skin template by default. This skin template is adapted to the applications for Windows Phone. The color of the text can be modified. Notes: - In this version, you cannot select a specific skin template: the controls use the system style. You can for example create buttons with a specific interface by using the clickable image controls.
- If the theme of Windows Phone is modified on the phone, the background color of the window is automatically modified. The color of the text is not modified: the text can become invisible.
Tip: Using an image control (whose size is identical to the window size) in window background. The image contained in this control will not be assigned by the change of theme.
Size of windows The size of the windows as well as their resolution are defined by Microsoft for the Windows Phone applications. These parameters cannot be modified: In edit, the DPI and size of the window are adapted for the comfort of the developer: therefore, the window is properly viewed in the editor. In the editor, the DPI is set to 160 and the size is set to 533 x 320. When creating the executable, the window is automatically adapted to the requirements of Microsoft. Note: The screen size (in inches) can change but the screen is always the same for the developer. Managing the "Back" and "Home" buttons Back button All the devices operating in Windows Phone include a special "Back" key (symbolized in most cases by a little arrow pointing to the left). In a WINDEV Mobile application, this key closes the current window and runs the window "closing" event. If the current window was the "last" window of the application, the project "Closing" event is is run. An application must be developed in order to behave properly if any of its windows is closed via the "Back" key. In most cases, each window control must be initialized with a default value and the "Back" button must be considered as being a "Cancel" button. Home button All the devices operating in Windows Phone include a specific "Home" key. In a WINDEV Mobile application, this key closes the current application and runs the project "Closing" event. An application must be developed in order to behave properly if any of its windows is closed via the "Home" key. In most cases, each window control must be initialized with a default value and the "Back" button must be considered as being a "Cancel" button. In the Windows Phone applications, the "Row selection" event in the loopers is run when the row is selected with a click. Note: The loopers are used to replace the tables in a Windows Phone application. Indeed, the concept of table does not exist in Windows Phone. The tables are not used in Windows Phone for the following reasons:: - The interface of tables is not appropriate.
- Problem regarding the space in the windows: the columns and the column headers would not be displayed.
- The row height would be too small to interact with it by touch.
- The tables are not used in the interface standard of this system.
Management of directories and character strings Managing directories The management of directories in Windows Phone presents the following specific features: - The application is installed in the setup directory. When running the application, the files used are created in the data directory associated with the application.
- Only the files found in the data directory associated with the application can be handled. You cannot handle the files or directories found at another location.
- The current directory corresponds to the data directory of application.
Managing character strings The default format of the character strings differs on Windows and on Windows Phone. In most cases, on the PCs, the Windows applications handle character strings in ANSI format. On Windows Phone, the applications handle character strings in UNICODE format.
