Hello Everyone, I have application that consist of three Tab Pane, I want to make the second tab be the default tab to appear.

I would really recommend taking some time to read the Textual documentation. Here's the link again to the TabbedContent docs: https://textual.textualize.io/widgets/tabbed_content

Hint: You probably want to check how to set the initial tab.

thanks, is active method do the same if yes can you provide simple example? and what is the difference between show_tab and active method?

active is a reactive -- if you assign an ID to it then the tab pane with that ID will become the active tab. You can see an example of this in the documentation that Tom recommended to you.
