Transparent components list background in Inno Setup?

I'm using custom installer to build "my own" setup.

Is it possible to create transparent background or disable background on comp开发者_StackOverflowonents list?

You can change the colour, border style, etc of the component list so you can handle any solid background colour, but not make it transparent. WizardForm.ComponentsList is a TNewCheckListBox for which you can see all properties in the "Support Classes Reference" in the help.
