Question: How can I make the items in my FMX `TListBox` bold? I can't find anything by myself, either in the documentation or the Internet.

Answer: 
Thanks to Gregg who gave a working answer for delphi, i'll put a C++Builder version here.

I made a loop over my ListBox with the item count, and it does not affect the loading speed of the ListBox (around 4000 items in my case) so it's a good solution at least for me.

```
ListBox->ListItems[x]->StyledSettings = ListBox->ListItems[x]->StyledSettings >> TStyledSetting::Style;
ListBox->ListItems[x]->Font->Style = ListBox->ListItems[x]->Font->Style << fsBold;

```
You can use custom theme for TListBoxItems. Create one by right mouse on ListBox.
