Attribute Description align * The align attribute specifies how child elements of the box are aligned when the size of the box is larger than the total size of the children. For boxes that have horizontal orientation, it specifies how its children will be aligned vertically. For boxes that have vertical orientation, it is used to specify how its children are aligned horizontally Acceptable values: Value Description start Child elements are aligned starting from the left or top edge of the box. If the box is larger than the total size of the children, the extra space is placed on the right or bottom side. center Extra space is split equally along each side of the child elements, resulting in the children being placed in the center of the box. end Child elements are placed on the right or bottom edge of the box. If the box is larger than the total size of the children, the extra space is placed on the left or top side. stretch The child elements are stretched to fit the size of the box. For a horizontal box, the children are stretched to be the height of the box. For a vertical box, the children are stretched to be the width of the box. aml:content * Name of locale key to substitute element's content. aml:draggable * Specifies wether element can be dragged by user. Acceptable values: Value Description true Element can be dragged. false Element can not be dragged. aml:droppable * Specifies wether element can be used as drop target. Acceptable values: Value Description true Element can be used as drop target. false Element can not be used as drop target. aml:resizable * Specifies whether element boundaries can be modified by user. Acceptable values: Value Description true Elements boundaries can be modified. false Elements boundaries can not be modified. aml:resize-edges * Specifies what edges can be resized. The attribute value is a space separated list of "top", "right", "bottom" and "left" tokens. aml:selectable * Enables/disables text selection on element. Acceptable values: Value Description true Text selection is enabled on element false Text selection is disabled on element inherit Text selection behavior is inherited from its parent container. aml:values * Semicolon-separated list of name:locale key pairs to substitute element's attributes or properties. For example: value:key_value;.innerHTML:key_innerHTML class * Element class. command * Set to the id of a command element that is being observed by the element. context * Should be set to the value of the id of the popup element that should appear when the user context-clicks on the element. debug * Draws a debug border around the box. Acceptable values: Value Description true For horizontally drawn elements the red border is shown, for vertically - the blue one. false flex * Indicates the flexibility of the element, which indicates how an element's container distributes remaining empty space among its children. Flexible elements grow and shrink to fit their given space. Elements with larger flex values will be made larger than elements with lower flex values, at the ratio determined by the two elements. The actual value is not relevant unless there are other flexible elements within the same container. Once the default sizes of elements in a box are calculated, the remaining space in the box is divided among the flexible elements, according to their flex ratios. Specifying a flex value of 0 has the same effect as leaving the flex attribute out entirely. height * The preferred height of the element in pixels. hidden * If set to true, the element is not displayed. This is similar to setting the CSS display property to 'none'. Acceptable values: Value Description true Element is visible. false Element is invisible. id * Element identifier. maxheight * The maximum height of the element. maxwidth * The maximum width of the element. minheight * The minimum height of the element. minwidth * The minimum width of the element. observes * Set to an id of a broadcaster element that is being observed by the element. If an attribute changes in the broadcaster it is also changed in the observer. on*** * Enables in-line handler for *** event. orient * Used to specify whether the children of the element are oriented horizontally or vertically. Acceptable values: Value Description horizontal Child elements of the element are placed next to each other in a row in the order that they appear in the XUL source. vertical Child elements of the element are placed under each other in a column in the order that they appear in the XUL source. pack * he pack attribute specifies where child elements of the box are placed when the box is larger that the size of the children. For boxes with horizontal orientation, it is used to indicate the position of children horizontally. For boxes with vertical orientation, it is used to indicate the position of children vertically. The align attribute is used to specify the position in the opposite direction. Acceptable values: Value Description start Child elements are placed starting from the left or top edge of the box. If the box is larger than the total size of the children, the extra space is placed on the right or bottom side. center Extra space is split equally along each side of the child elements, resulting the children being placed in the center of the box. end Child elements are placed on the right or bottom edge of the box. If the box is larger than the total size of the children, the extra space is placed on the left or top side. stretch The child elements are stretched to fit the size of the box. popup * Should be set to the value of the id of the popup element that should appear when the user clicks on the element. tooltip * Should be set to the value of the id of the popup element that should be used as a tooltip window when the mouse hovers over the element for a moment. tooltiptext * Used to set the text which appears in the tooltip when the user moves the mouse over the element. width * The preferred width of the element in pixels. xml:base * Retrieves baseURI for the object. xml:space * Instructs DOM implementation on weather to preserve whitespace text nodes.
