Which of the following UI controls is used to display multi-line wrapped text?
Answer(s): D
The TextArea control is a multi-line text field that has a border and optional scroll bars. The features of the TextArea control are as follows:· It supports the HTML rendering capabilities of Flash Player and AIR. · It displays its contents in the color specified by the disabledColor style when the user disables the TextArea control.· It can also be set to read-only to prohibit text editing. · It hides input password text (****) when the user sets the TextArea's displayAsPassword property.Answer option B is incorrect. The TileList control displays a list of items present in the tiles. It shows a scroll bar on one of its axes to access all items in the list, depending on the direction property. A user can set the size of the tiles by using the rowHeight and columnWidth properties.Answer option A is incorrect. The Textlnput control is a single-line text field that controls text formatting, validation, and keyboard equivalents. It has many states such as filled, selected, disabled, and error. The Textlnput control supports the HTML rendering capabilities of Flash Player and AIR.Answer option C is incorrect. The DataGrid control is a sub class of the list-based control. It can display one or more columns of data. It is used to represent the data in the tabular form, and allow users to scroll the selected data easily. Users can edit the DataGrid control and multiple rows of data in batches without navigation.
Which of the following statements are correct about device fonts? Each correct answer represents a complete solution. Choose two.
Answer(s): A,C
Fact What are embedded fonts?Embedded fonts can be used for both dynamic and input text fields. These fonts are stored in a SWF file. So, Flash Player uses the stored font information to display the fonts even if they are not available on the end user's computer. As the player uses embedded fonts, the fonts look exactly the same as expected. Since the embedded fonts are embedded in the SWF file, the size of the Flex application is greater as compared to the file in which device fonts are used. It supports advanced anti-aliasing and font rotation.
Which of the following skins consists of a constructor, an updateDisplayList() method, and a set of getters and setters for the skins properties?
Answer(s): C
The Programmatic skin consists of a constructor, an updateDisplayList() method, and a set of getters and setters for the skin's properties. Skin is the process of applying a set of graphics visual components. These visual components may be made up by bitmap images, SWF files, or class files, etc. Skin can define the entire appearance, or only a part of the appearance, of a component in various states. Various types of skins are available, which are as follows:· Graphical skin: A Graphical skin is an image that is designed to replace the default appearance of a Flex visual component.· Programmatic skin: A Programmatic skin is also known as Vector graphic skin. It consists of a constructor, an updateDisplayList() method, and a set of getters and setters for the skin's properties.· Stateful skin: A Stateful skin is the type of programmatic skin that uses view states, where each view state corresponds to a state of the component.
Which of the following components is used to represent a server-side Java class containing public methods you want to call from a Flex application?
RPC represents a software architecture that allows an application in one operating environment to cause methods to be executed in separate, remote operating environments. This architecture can be implemented in Flex with a dynamic Web server, which can respond to HTTP requests. There are following components in an RPC-style architecture:FactWhat is RPC?RPC (Remote procedure call) is an inter-process communication technology that allows a computer program to cause a subroutine or procedure to execute in another address space (commonly on another computer on a shared network) without the programmer explicitly coding the details for this remote interaction. That is, the programmer would write essentially the same code whether the subroutine is local to the executing program, or remote. When the software in question is written using object-oriented principles, RPC may be referred to as remote invocation or remote method invocation. Answer option B is incorrect. The AdvancedLegend component is not a valid component.
You want to let the flash player make the embedded form more readable by smoothing the font edges during the rendering process. Which of the following options will you set to accomplish the task?
According to the question, you want to let the flash player make the embedded form more readable by smoothing the font edges during the rendering process. Therefore, you will use the fontAntiAliasType style.Advanced anti-aliasing is the ability of Flash Player to make embedded fonts more readable. Flash does it by smoothing the fonts edges during the rendering process. By default, the fontAntiAliasType style is set to advanced when a developer embeds a font. Advanced anti-aliasing can be set by using the following syntax:@font-face {src:source('Garamond");font-family:"GaramondWithoutAntialiasing';font-anti-alias-type:advance;}
