I was hoping for a way to manually set the border property on certain components, like the Drowdown List, through expression or the Border chooser on the border property.
Some components have a preset property that says “Other Border”. I would like to do a conditional expression to set a red line around the border with the same look it has, else keep it the way it is by default. I tried selecting many combinations of options, but couldn’t replicate the default.
Otherwise, some workarounds are to put a rectangle of the same size of the component, set the fill opacity to zero or possibly get into the java swing code, but unable to find good resources or examples.
