public void setContents(String contents)
When 'dynamicContents'
is set, setContents()
can also be called with no arguments to cause contents to be re-evaluated.

- an HTML string to be set as the contents of this widget. Default value is " "public String getContents()
getContents
in class Canvas
public void setDynamicContents(Boolean dynamicContents)
You can use this feature to build some simple custom components. For example, let's say you want to show the value of a Slider in a Canvas somewhere on the screen. You can do this by observing the valueChanged() method on the slider and calling setContents() on your canvas with the new string or you can set the contents of the canvas to something like:
"The slider value is \${sliderInstance.getValue()}."
Next you set dynamicContents: true on the canvas, observe valueChanged() on the slider and call canvas.markForRedraw() in that observation. This approach is cleaner than setContents() when the Canvas is aggregating several values or dynamic expressions. Like so:
Slider.create({ ID: "mySlider" }); Canvas.create({ ID: "myCanvas", dynamicContents: true, contents: "The slider value is \${mySlider.getValue()}." }); myCanvas.observe(mySlider, "valueChanged", "observer.markForRedraw()");You can embed an arbitrary number of dynamic expressions in the contents string. The search and replace is optimized for speed.
If an error occurs during the evaluation of one of the expressions, a warning is logged to the ISC Developer Console and the error string is embedded in place of the expected value in the Canvas.
The value of a function is its return value. The value of any variable is the same as that returned by its toString() representation.
Inside the evalution
contentext, this
points to the canvas instance that
has the dynamicContents string as its contents -
in other words the canvas instance on
which the template is declared.
Note : This is an advanced setting
