Methods and systems which may implement buffer swapping are provided. The methods include rendering, onto screen locations of a display screen, data from a memory having a first buffer and a second buffer, each buffer having respective buffer memory locations which correspond to the screen locations of the display screen. The methods can include: rendering first data from the first buffer onto the display screen; writing, to the second buffer, second data based on at least some of the first data from the first buffer by performing at least one of transforming at least some first data and changing corresponding screen locations of at least some first data from the first buffer, by writing at most once to each buffer memory location of the second buffer; and rendering the second data from the second buffer onto the display screen.

Method and system for displaying using buffer swapping

Prompting user confirmation of an action in a display window on a display of a mobile electronic device including displaying a pair of soft key icons, receiving a request to initiate an action from a user and displaying a confirmation message to confirm that a user wishes to proceed with the action. When the confirmation message is displayed, the pair of soft key icons are modified to create a pair of updated soft key icons. The receiving of the request may include detection of a soft key event. The updated soft key icons provide a first response and a second response to the confirmation message for selection by the user. The soft key icons and updated soft key icons may be displayed at the bottom portion of the display in a manner that does not obstruct the display window.

Method for prompting user confirmation

Navigation between a plurality of property sheets on a display of a mobile electronic device, each of the property sheets having a tab index and a layout defining a plurality of elements. One of the property sheets is a displayed property sheet and one of the elements is a current active element. Navigation includes (i) storing the tab index of the displayed property sheet as a current tab index; (ii) detecting a soft key event; regardless of which of the elements is a current active element, (iii) modifying the current tab index based on a soft key identifier of the soft key event to create an updated tab index; and (iv) displaying another property sheet of the plurality of property sheets on the display, the another property sheet having a tab index equal to the updated tab index.
