ToolBar style attributes
ToolBar presentation style attributes apply to the TOOLBAR
element.
aspect
Defines the aspect of the toolbar, by specifying the visibility or the relative position of the icon and text of a toolbar item.
"iconAboveText"
(default): The icons are displayed on top of the texts."icon"
: Only toolbar item icons are displayed. When no icon is available, displays the text."text"
: Only toolbar item texts is displayed."iconAndText"
: The icons are displayed to the left of the texts.
aspect
attribute is ignored for this list).itemsAlignment
Defines how toolbar items must be aligned for the available space.
"left"
(default): Items are compacted to the left."center"
: Items are compacted and centered."right"
: Items are compacted to the right."justify"
: Items are equally stretched to occupy all available space.
scaleIcon
Defines the scaling behavior of the associated icon, if the source image size is bigger than the place reserved for it in the widget.
If the scaleIcon
attribute is undefined, the behavior depends on the type of
action view: toolbar button icons and action panel button icons are scaled down to match the size of
the widget. For other widgets, by default no scaling occurs, as for
scaleIcon="no"
.
"no"
: No scaling occurs and the image is taken as-is. It is up to the developer to resize the source image to avoid misalignment."yes"
: Images are scaled down following the height of the widget (button or edit field). Setting a big font can result in a big icon.
Independently of the scaleIcon
attribute value,to avoid pixelization or
blurring of images, raster images are never upscaled. However, SVG images and TTF icons can
be upscaled without any penalty.
If the icon must be enlarged, the image is centered and a transparent border is added to "fill" the empty space. This allows a mix of larger and smaller icons while keeping widget alignment.
If scaling takes place, the aspect ratio of the original image is kept. A non-square source image displays as a non-square scaled icon.
size
Specifies an abstract size for the toolbar.
"small"
: Displays toolbar items with a small size, allowing a maximum of items to be displayed."medium"
(default): Displays toolbar items with a regular size."large"
: Displays large toolbar items, showing only a handful of buttons.
The number of toolbar items displayed with these different size specifications depends on the
size of the screen. For example, on a mobile device screen, "small"
will show about
seven toolbar items (buttons). This will also depend on the screen orientation.
