Rectangle Frame widget?

[CHech.1]

Hi,

I'm working on a project that has to support highlighting "focused" components with a frame around them.

The buttons have images, so I need the "inside" of the frame to be transparent.

BoxWithBorder doesn't suit my needs, as I can't set the inside to be transparent and the border not to be (right?)

Is there a recommended way to do this without creating a widget from scratch?

Thank you!

Hi,

Unfortunately not that I am aware of. What I would do instead of creating a widget through code is to do a custom container instead where you use 4 box widgets to do the borders without alpha and either nothing or a box for the inside with alpha. You could always make it more intelligent through user code to have it adapt to the size of the images.

It's easy to derive class from that widget, and override draw() function, like this

virtual void draw(const touchgfx::Rect& invalidatedArea) const;

{

parent widget‘s draw();

draw your box; //your box will NOT exceed the width and height of widget

}

​may not work， just a hint.
