Basic Properties Tab

The Basic properties tab contains controls for determining the name of the object as well as its position, size and visibility on the page:

Name

Sets the name of the object.

TIP: To avoid issues with HTML rendering of the object, don't use spaces or symbols and ensure the name starts with a letter.

X pos

Sets the horizontal position of the object on the page. This is measured in pixels from the left edge of the page to the left edge of the object.

Y pos

Sets the vertical position of the object on the page. This is measured in pixels from the top edge of the page to the top edge of the object.

Width

Sets the width, in pixels, of the object.

Height

Sets the height, in pixels, of the object.

TIP: The position and size of the object can also be set by dragging and resizing the object in the Design Area preview.

Visible

Determines whether the object will be visible on the page when the page first loads. When ticked, the object will be visible. When un-ticked, the object will be invisible. Behaviours can be used to make the object visible if it is not already.

Opaque

Determines whether the object will be opaque (or transparent) when the page first loads. When ticked, the object will be opaque. When un-ticked, the object will be transparent. Behaviours can be used to make the object opaque if it is not already.

TIP: It is important to understand the difference between an object that is invisible and an object that is transparent. An invisible object is not present on the page and cannot be interacted with. A transparent object is present on the page but cannot be seen; it can be interacted with, though. For example, if you need to detect that the mouse pointer has entered an object that cannot be seen, it needs to be set to transparent rather than invisible.
