Configuring user interfaces in electronic devices
A method and an electronic device arranged to execute application programs, wherein the device comprises an operating system enabling a separation of user interface data from the rest of the data processing system, the device being arranged to check, in response to starting an execution of the application program, whether screen size information of the application program corresponds to a display size of the terminal; and download, in response to the screen size of the application program differing from the display size of the terminal, a new user interface file with an appropriate screen size from a network server.
1. A method comprising:
starting an execution of an application program in a terminal comprising an operating system enabling a separation of user interface data from the rest of a data processing system;
checking at the terminal whether screen size information of the application program whose execution has been started in the terminal corresponds to a display size of the terminal; and
in response to the screen size of the application program differing from the display size of the terminal, downloading from a network server a new user interface file containing a user interface descriptor with an appropriate screen size for use by said application program so as to correspond to the display size of said terminal.
2. The method according to claim 1 , further comprising:
prior to downloading the new user interface file from the network server, examining whether the application program includes any further user interface files; and
selecting a user interface file appropriate for the terminal for further usage, if included in the application program.
3. The method according to claim 1 , wherein the application program includes a network address of the network server providing user interface files to be downloaded.
4. An electronic device comprising:
a data processing unit;
a memory, coupled to said data processing unit, for storage of an operating system and application programs, said operating system enabling a separation of user interface data from the rest of data processing operations;
an input/output interface coupled to said memory and data processing unit;
the data processing unit being configured to check, in response to starting an execution of one of the application programs in a terminal, whether screen size information of the application program whose execution has been started in the terminal corresponds to a display size of the terminal; and
the input/output interface being configured to download from a network server, in response to the screen size of the application program differing from the display size of the terminal, a new user interface file containing a user interface descriptor with an appropriate screen size for use by said application program so as to correspond to the display size of said terminal.
5. The device according to claim 4 , the device being further configured to:
examine, prior to downloading the new user interface file from the network server, whether the application program includes any further user interface files; and
select a user interface file appropriate for the terminal for further usage, if included in the application program.
6. The device according to claim 4 , wherein the device is configured to retrieve a network address of the network server from a predefined location in the application program.
7. The device according to claim 4 , wherein the operating system is the Symbian operating system.
8. A computer program product, stored on a non-transitory computer readable medium and executable in a data processing device, for updating a user interface file for an application program, the computer program product comprising:
a computer program code section for starting an execution of the application program in a terminal;
a computer program code section for checking whether screen size information of the application program whose execution has been started in the terminal corresponds to a display size of the terminal; and
a computer program code section, responsive to the screen size of the application program differing from the display size of the terminal, for downloading from a network server a new user interface file containing a user interface descriptor with an appropriate display size for use by said application program so as to correspond to the display size of said terminal.
9. The computer program product according to claim 8 , further comprising:
a computer program code section for examining, prior to downloading the new user interface file from the network server, whether the application program includes any further user interface files; and
a computer program code section for selecting a user interface file appropriate for the terminal for further usage, if included in the application program.
10. The computer program product according to claim 8 , further comprising:
a computer program code section for retrieving a network address of the network server from a predefined location in the application program.
11. The computer program product according to claim 8 , wherein the computer program product is compatible with Symbian operating system.
