Description

The Panel control displays HTML or a Form in a panel that floats on top of the current form. It can be animated to appear from the left or right.

To add a Panel to your app, choose the Panel icon in the Toolbar, then position it on the Design Screen. Use the Property Editor to set the properties you need.

If a form is opened in a Panel, NSB.currentForm is set to the new form and the form's onshow() function is called. When the Panel is closed, the onhide() function is called and NSB.currentForm is set to the previous form. The size of the form is adjusted to be equal the size of the panel.

On iOS, Panels do not close if you click outside them. The solution is to turn off FastClick in Project Properties.

Properties

Standard properties are supported, plus:

animate Sets whether the panel will animate when opening and closing. If set to false, the panel will just appear and disappear without animation. This is recommended for fastest performance. Design time.
close() Closes panel. Runtime.
dismissable Sets whether the panel can be closed by clicking outside onto the page. Design time.
display The relationship of the panel to the page contents. Default is 'overlay" for the panel to appear on top of the page contents. 'reveal': the panel will sit under the page and reveal as the page slides away. "push" animates both the panel and page at the same time. Design time.
open([form]) Opens form in the panel. If form is blank, uses contents of text property. Runtime.
position Should the panel appear on the left or right of the screen? Design time.
positionFixed Sets whether the panel has fixed positioning so the contents are in view even if the page is scrolled down. This also allows the page to scroll while the panel stays fixed. Design time.
previousForm A reference to the form which will be returned to when the panel is closed. Runtime.
text The text to display on the form. Can be HTML. Leave blank if using Form1.open(Form2). Design time.
