Arrange Objects

Every object on the screen has its own Z-position, ie� an order of objects along the Z-axis, which

is perpendicular to the screen� Consider each object as a single sheet in a stack�

When the Form is being constructed, by default, the objects are arranged in order from the top

of the Form with each new object being added beneath the last one on the Form, but ahead or

in front of the former object in the Z-axis�

It may be useful, (in the interests of saving screen real estate), to arrange objects in a stack� Use

the Arrange popup menu, which opens when the Arrange button is tapped�

Bring to Front� takes any object from the stack and puts it at the forefront position�

Bring Forward swaps the object with the closest object forward of it, if any�

Send to Back puts the object to the furthest position rearward�

Send Backward swaps the object with the closest object rearward of it, if any�

Please note that Z-ordering for Popup tags behaves opposite to that of Event Buttons�

Popup tags always follow their target Event when the Event’s Z-order is changed�

Remove an Object

Select an object and tap the trash icon in the lower-right corner of the screen�

Links

A Link is used to automatically activate or deactivate buttons in a CODA Form as a consequence

of how the activity is unfolding� A link may also pass Tag information from a source Tag to a

target Event when the link activates or deactivates the target Event�

The benet of using Links is to reduce the number of manual button activations and/or

deactivations, (clicks) that an operator would need to perform� The use of links in the Form will

make the coding of your activity more ecient�

Links can be initiated when an Event, Tag or Popup Tag button is activated (button clicked down)

or when an Event button is deactivated (button clicked up)�

Link Protocols

A Link may be used to “activate” or “deactivate” a button�

A Link will not be activated unless the Source button is active�

A Link to a Tag button may tag or pass its tag as well as activate the button�

A link will only work in the direction of the link�

A link may be established

– from an Event button to another Event button or to a Tag button

– from a Tag button to an Event button or to another Tag button
