I am at the beginning of scoping a large web application with
Flex, which in all likelihood will be made up of many custom
components (both MXML and AS classes).
My question is, if a component is not derived from an
existing control, is there any way to create a base preview of that
component when dragging and placing it into design view?
For example, I created a temperature monitoring control that
is derived from Canvas - basically because I just wanted a blank,
uh, canvas to draw the graphics on. But dragging this new control
onto the design page just shows an empty box.
Obviously if I create a lot of the UI with custom components
like this I won't be able to see what I am doing!
Is there a way for me to draw the default look of the control
when placing it into design view? How does Flex Builder draw the
design-mode/default look of the built-in controls, like buttons or
datagrids? Even just a static GIF or PNG image would be helpful to
see where I am placing things.
