Re: JSplitPane resize woes

Show key headers only | View raw

Hi Experts,

I have an issue with my JSpiltPane. Below is the code snippet.
Problem is I have one panel added in Right side of the Spilt Pane, and that Panel has many components like Label,TextArea,Panel,Checkbox etc. And this panel is itself a Titled Border Panel.

When I am maximizing my screen, the Right side panel is not resizing. I tried a lot with the layouts but no Luck.

Would be great if someone can help me on this.
