How To Set a FMX.Panel Color?

Question

FMX controls do not have a color property. What is the FMX equivalent to VCL.TColor?

FMX.Panel1.Color := clBlack

Answer 1

Quoting myself: in a nutshell, use a TRectangle instead of a TPanel (a panel's style is probably composed of a TRectangle anyway):

1. Add a TRectangle to the form.
2. Change Stroke.Color to Gray.
3. Change Fill.Color to whatever you want.
4. At runtime, change the colour with code like this:

MyRectangle.Fill.Color := TAlphaColors.Blue;

Annoyingly, at designtime, a TRectangle is made to pretend it can’t parent other controls (in reality, any FMX control can parent any other). However, you can use the Structure pane top left of the IDE to reparent controls to it as you wish.

Answer 2

I found a better way : -define the panel as needed -put all necessary controls inside it -add in it a Rectangle of the same size as the panel -set its Fill Property to the colour you want -send the rectangle to the back so other controls will be visible

This way, it looks like the panel has a Fill colour, but it functions as a panel, e.g. all controls within it can be made not visible at the same time, etc.
