CWC2 Attribute Groups

The name of the widget. Not all widgets use this. Only the SharedResource widget currently needs this. The type of the widget indicates the actual widget object to create for this tag. Make the widget visible or not in the page, by default this is true for all widgets. Setting this to true will typically result in some HTML comment being written into the page in place of its normal user interface. Note that setting a widget to invisible will not prevent the widget from outputting form variables and javascript. To remove a widget entirely (without deleting it), set its ENABLED property to false. Never attempt to comment out a widget tag using HTML comments in the template. Enable or disable the widget in the interface. If the widget is disabled, then this should result in all output from the widget being removed from the resulting template. It should be used to temporarily remove a widget from normal processing, while leaving a placeholder in the template. Never attempt to comment out a widget tag using HTML comments in the template. The text to display in this label. This should contain valid HTML. Special characters, such as accented characters, must be represented by their HTML encoded version (i.e. é is é). The position of the label around another widget. Position 0 is upper-left. Positions increase clockwise to position 8 which is left of the widget. Default is 8. The horizontal alignment of the label, default is left. The vertical alignment of this label. The default is middle. The CSS class to control the rendering of this label. The default is CWCLabelWidgetClass. The CSS style to apply to this label. The default is no style. The image to display for this icon. The width in pixels of this image. This is used in the resulting <IMG> tag to allow some browsers (like Netscape 4.7) to load the page faster. The height in pixels of this image. This is used in the resulting <IMG> tag to allow some browsers (like Netscape 4.7) to load the page faster. The alternate or tooltip text to display for this image. Not all browsers support this property. The CSS class to control the rendering of this image. The default is no class. A CSS style to apply to this image tag. The default is no style. A name indicating a logical group of tools of which only one can be selected. The image to display when this button is selected. The image to display when the mouse hovers over this button. Sets the width in pixels of a popup window. Sets the height in pixels of a popup window. Controls the display of a toolbar in a popup window. The default is true. Controls the display of a menubar in a popup window. The default is true. Controls the display of a status bar in a popup window. The default is true. Controls the display of scrollbars in a popup window. The default is true. Controls if a popup window is resizable or not. The default is true. The color to fill the background of the text button with. An image to render as the background of the button. The background image is rendered on top of the background color. The image to use as the top left corner of the text button. The image to use as the top edge of the button. The image to use as the top right corner of the text button. The image to use as the right edge of the text button. The image to use as the bottom right corner of the text button. The image to use as the bottom edge of the text button. The image to use as the bottom left corner of the text button. The image to use as the left edge of the text button The overall width of the text button in pixels. The overall height of the text button in pixels. The amount of space to leave between the image and the label in pixels. The amount of vertical adjustment in pixels to apply to the label's vertical placement. The label is centered vertically in the available space but may sometimes appear misaligned because of rounding errors or descenders (qypgj). Path to the TrueType font file to use when rendering the label. The path is specified relative to the cwc2 directory. The font file must exist on the server to be valid. The size of font to use for the label. The horizontal alignment of the label on the button. One of left, center or right. Control the use of antialiasing when rendering the label. This is sometimes desirable to control the quality of the font rendering. The image to display in the button. The image is displayed at the left edge of the button, centered vertically. Control the use of caching when rendering text buttons. Text buttons take a relatively long time to render so it is desirable to cache the text button for improved application performance. However, when developing a new template or modifying existing buttons, it is useful to turn off caching temporarily.
