WkImageWidget
WkImageWidgets provide a mechanism for displaying an image with an optional label. They call their default action callback when they are double clicked upon. The image and text labels may be layed out either vertically or horizontally. Different images and labels can be specified for the up state and the disabled state. An optional inset or outset border may also be specified.

Example
The following example code creates a WkImageWidget where the image is composed of an icon (from a file) and a text label laid out vertically. This corresponds to the upper left image at the start of the WkImageWidget section.
aWkImageWidget := WkImageWidget
createWidget: 'aWkImageWidget'
parent: self form
argBlock: [:w | w
x: 52;
y: 44;
width: 136;
height: 80;
image: (WbLabeledImage stateDriven
image: (WbIcon fromFile: 'BALLOON.ICO')
label: 'Balloon';
orientation: XmVERTICAL;
yourself);
scale].
The next example code creates a WkImageWidget where the image is composed of an icon (from a file) and a text label laid out horizontally with an outset shadow type. This corresponds to the lower right image at the start of the WkImageWidget section.
aWkImageWidget := WkImageWidget
createWidget: 'aWkImageWidget'
parent: self form
argBlock: [:w | w
x: 52;
y: 44;
width: 136;
height: 80;
image: (WbLabeledImage stateDriven
image: (WbIcon fromFile: 'BALLOON.ICO')
label: 'Balloon';
yourself);
orientation: XmHORIZONTAL;
shadowType: XmSHADOWOUT;
shadowType: XmSHADOWOUT;
