Abstract: Example implementations relate to cloud topology visualizations. In example implementations, node models may be received from a plurality of model repositories. The received node models may correspond to nodes in the same cloud topology. Each of the plurality of model repositories may be associated with a respective model-specific format and a respective cloud provider. Each of the received node models may be in a model-specific format associated with the respective model repository from which the node model was received. The respective model-specific format of each received node model may be translated into a generic format. The generic-format node models may be sent to a topology visualizer. The topology visualizer may generate, based on the generic-format node models, a visualization of the cloud topology.

Abstract: A system and method for changing the methods of an object based on the mode of the application. Two types of dictionaries are used, a first type which defines all of the methods for an object for a particular mode and a second type which defines all of the modes supported by an application. In addition, a variable can be used to store the dictionary of methods for the current mode. This invention uses object oriented programming techniques.

Abstract: A tool for a display system comprises means for superimposing a box on a portion of a buffer of data visible on a display; the box being representative of the size and location of the visible portion with respect to the whole of the buffer. For example, a box of an appropriate size can be superimposed on a portion of a buffer of data displayed in a window at an appropriate location in the window to allow the two-dimensional extent of the visible portion of the buffer with respect to the rest of the buffer of data to be represented in an easily understood manner. The invention finds particular application as part of a scroll tool. By the provision of means for interacting with the scroll box the user is provided with a user-friendly manner of scrolling around a document in a plurality of directions. This scroll tool is much more convenient to use than conventional scroll bars and does not take up unnecessary screen real estate.

Abstract: The system and method provides a user interface tool for simultaneously selecting a menu item and a value, from a range of values, for the menu item. The user interface tool is referred to as a valuator menu, since it allows both the selection of a value from a range of values, and the selection of a menu item from a menu list. As a user moves a cursor over a menu of selectable items on a screen display, the item underneath the cursor is highlighted. In addition, as the user moves the cursor within the highlighted menu item, a value relative to the position of the cursor within that menu item is displayed. This valuator value is dynamically updated as the cursor position changes within the menu item. When the user performs an input selection, i.e. through a mouse button or a keyboard interaction, both the selected menu item and the value, relative to the cursor position, are simultaneously returned to the application program running on the data processing system.
