Frequently Asked Question for NetBeans

1 Why do my frames appear differently at run-time?

The page sizes will not change once created if you change the frameset. If that were to happen it would risk destroying a layout or corrupting the content. It would also be inflexible as it would tie the content to the frames. Since the content of the frameset can be controlled programmatically there is also no way of knowing where a page will be used, and in fact it could be used in multiple locations, nested within another page or even reused in another project.

There is a popup menu item for the page that allows the preferred page size to be set, and the default sizes that this popup list should reflect the current frame settings.

When the project is run the page layout depends not just of the sizes specified for the frameset, but also on the layout managers and these may resize the content. Some layout managers may also be influenced by the content and therefore the final layout can vary.
