TDBNavigator background transparency color error

Question

When I add a TDBNavigator to my project, and mark the option FLAT = TRUE, immediately the background colour of my TDBNavigator changes to black, totally losing its characteristic.

When I run the application, TDBNavigator is as shown in the picture, black.

How to solve this problem?

I am using the c++ builder 10.3.3

Answer 1

With 10.4.1 and clang compile a runtime TDBNavigator icon background is black. I opened an issue https://quality.embarcadero.com/browse/RSP-31245

Answer 2

I got an alternative. It seems to me a problem with the transparency of these components.

When I insert a TPanel in the toolbar, the same problem occurs. But in TPanel, I have a ParentBackGround property. When I mark it as false, the background of the TPanel becomes transparent again.

So I used the following alternative.

• 1 - Insert a TPanel into the toolbar

• 2 - Place the ParentBackground TPanel property = false

• 3 - Move TDBNavigator into the TPanel

• 4 - Change the TPanel properties:

  a) BevelEdger = false (all) b) Autosize = true c) BorderStyle = bsNONE d) BevelInner = bsNONE e) BevelKInd = bsNONE f) BevelOuter = bsNONE g) Delete CAPTION from panel

• 5 - Change FLAT property of TDBNavigator to TRUE;

That's how it worked.
