Information processing apparatus, method of controlling the same and non-transitory computer-readable storage medium

1. An information processing apparatus that has a display unit and a plurality of graphic controllers, the apparatus comprising:

at least one processor and a memory storing instructions which, when executed by the at least one processor, cause the information processing apparatus to:

cause the display unit to display, using a graphic controller corresponding to an application of the plurality of graphic controllers, a screen of the application;

detect an event that is generated by a user operation to the screen displayed on the display unit;

determine, when the event is detected, the graphic controller corresponding to the application displaying the screen on the display unit; and

based on a resolution of the display unit and information of the graphic controller for which the determination is made, convert coordinate information on the display unit of the user operation that the event indicates to a value of a coordinate system corresponding to the graphic controller for which the determination is made, and transmit a result of the conversion to the application.

2. The information processing apparatus according to claim 1 , wherein

as the event, a value in a coordinate system for the display unit on which the user operation is performed is detected, and

based on the resolution of the display unit and information of the graphic controller for which the determination is made, the coordinate information on the display unit of the user operation that the event indicates to the value of the coordinate system for a screen being displayed on the display unit.

3. The information processing apparatus according to claim 1 , wherein

based on a size of a screen that the application is displaying on the display unit, the coordinate information of the user operation that the event indicates is converted to the value of the coordinate system corresponding to the graphic controller corresponding to the application.

4. The information processing apparatus according to claim 1 , wherein

the plurality of graphic controllers comprises

a first graphic controller configured to be used by a C application which is implemented in a C language and

a second graphic controller configured to be used by a Java application which is implemented in a Java language.

5. The information processing apparatus according to claim 4 , wherein

in a case when the application being displayed on the screen is determined to be a C application and the resolution of the display unit is a first resolution at which the application is displayed on the entirety of the screen, the coordinate information of the user operation that the event indicates is not converted, and

in a case when the application being displayed on the screen is determined to be a C application and the resolution of the display unit is a second resolution at which a display region in which the screen of the application is displayed and a display region in which other display content is displayed are included, the coordinate information of the user operation that the event indicates is converted based on a difference between the first resolution and the second resolution, and

in a case when the application being displayed on the screen is determined to be a Java application, and the resolution of the display unit is the first resolution, the coordinate information of the user operation that the event indicates to a value of a coordinate system corresponding to the second graphic controller is converted, and

in a case when the application being displayed on the screen is determined to be a Java application, and the resolution of the display unit is the second resolution, coordinate information of the user operation that the event indicates to a value of a coordinate system corresponding to the second graphic controller is further converted based on the difference between the first resolution and the second resolution.

6. A method of controlling an information processing apparatus that has a display unit and a plurality of graphic controllers, the method comprising:

causing the display unit to display, using a graphic controller corresponding to an application of the plurality of graphic controllers, a screen of the application;

detecting an event that is generated by a user operation to the screen displayed on the display unit;

determining, when the event is detected, the graphic controller corresponding to the application displaying the screen on the display unit; and

based on a resolution of the display unit and information of the graphic controller for which the determination is made, converting coordinate information on the display unit of the user operation that the event indicates to a value of a coordinate system corresponding to the graphic controller for which the determination is made, and transmitting a result of the conversion to the application.

7. A non-transitory computer-readable storage medium storing a program for causing a computer that has a display unit and a plurality of graphic controllers to execute a method, the method comprising:

causing the display unit to display, using a graphic controller corresponding to an application of the plurality of graphic controllers, a screen of the application;

detecting an event that is generated by a user operation to the screen displayed on the display unit;

determining, when the event is detected, the graphic controller corresponding to the application displaying the screen on the display unit; and

based on a resolution of the display unit and information of the graphic controller for which the determination is made, converting coordinate information on the display unit of the user operation that the event indicates to a value of a coordinate system corresponding to the graphic controller for which the determination is made, and transmitting a result of the conversion to the application.
