Information processing apparatus, display control method, and program
View Patent ↗According to one embodiment, an information processing apparatus having an internal display and a connection module for an external display, includes a storage module configured to store items of virtual desktop information to be displayed on an actual display screen of one of the internal display and the external display and items of information of a display which displays the items of virtual desktop information in association with each other, and a control module configured to read out, from the storage module, an item of virtual desktop information in association with the external display and to supply the item of virtual desktop information in association with the external display to external display upon detecting that the external display is connected to the connection module when one of the items of virtual desktop information is displayed on the actual display screen of the internal display.
1. An information processing apparatus comprising an internal display and a connector for an external display, comprising:
storage configured to store definition information representing which virtual desktops are to be displayed by the external display or the internal display;
an external display controller configured to read out first definition information representing that a first virtual desktop is to be displayed by the external display device from the storage, and to supply the first definition information to the external display when a connection of the external display to the connector is detected and a second virtual desktop is displayed on the internal display;
an internal display controller configured to read out second definition information representing that a third virtual desktop is to be displayed at the internal display device from the storage, and to supply the read second definition information to the internal display when a switching request is received and a fourth virtual desktop is displayed on the internal display; and
a writing module configured to update the definition information such that the definition information represents that a fifth desktop is to be displayed at the external display when a disconnection of the external display from the connector is detected and the external device displays the fifth desktop.
2. The apparatus of claim 1 , further comprising:
a buffer memory configured to temporarily store the virtual desktops, wherein
the virtual desktops stored in a main memory are copied to storage areas of the buffer memory for the internal display and the external display and then send to the internal display and the external display.
3. A display control method for an information processing apparatus comprising an internal display and a connector for an external display, comprising:
storing in storage definition information representing which virtual desktops are to be displayed by the external display or the internal display;
reading out first definition information representing that a first virtual desktop is to be displayed at the external display device from the storage, and supplying the read first definition information to the external display when a connection of the external display to the connector is detected and a second virtual desktop is displayed on the internal display;
reading out second definition information representing that a third virtual desktop is to be displayed at the internal display device from the storage, and supplying the read second definition information to the internal display when a switching request is received and a fourth virtual desktop is displayed on the internal display; and
updating the definition information such that the definition information represents that a fifth desktop is to be displayed at the external display when a disconnection of the external display from the connector is detected and the external device displays the fifth desktop.
4. A computer readable non-transitory storage medium having a computer program stored thereon for an information processing apparatus comprising an internal display and a connector for an external display, wherein the computer program causes the information processing apparatus to execute functions comprising:
storing in storage definition information representing which virtual desktops are to be displayed by the external display or the internal display;
reading out first definition information representing that a first virtual desktop is to be displayed at the external display device from the storage, and supplying the first definition information to the external display when a connection of the external display to the connector is detected and a second virtual desktop is displayed on the internal display;
reading out second definition information representing that a third virtual desktop is to be displayed at the internal display device from the storage, and supplying the second definition information to the internal display when a switching request is received and a fourth virtual desktop is displayed on the internal display; and
updating the definition information such that the definition information represents that a fifth desktop is to be displayed at the external display when a disconnection of the external display from the connector is detected and the external device displays the fifth desktop.
