Overview
The Slide object is used to present multiple visual stimuli (e.g., text, multiple images, text and images, buttons, sliders, etc.), or combinations of text, images, and sound concurrently. The Slide object holds a collection of SlideState objects, which are used to organize the presentation of stimuli. Individual stimuli composing a single presentation event are entered on SlideStates using sub-objects. This hierarchy of objects permits tremendous flexibility in the presentation of stimuli.
The Slide object as it appears in the Toolbox.
Properties are set independently for the Slide object, each of its child SlideState objects, and their sub-objects. The parent object (i.e., Slide) maintains parameters relevant to the duration of the object, the collection of input, and termination conditions.
Watch Slide objects and sub-objects for more information.
Interface
A new Slide object may be created by clicking the Slide icon in the Toolbox, and dragging the object to the Workspace. For existing Slide objects, clicking the object once with the mouse in the Structure view to select it will result in the display of that object’s properties in the Properties window. Double clicking an existing Slide object in the Structure view will open the Slide in the Workspace, and the properties for that object will be displayed in the Properties window.
A Slide object opened in the Workspace displays the name of the object and the Slide object icon in the title bar at the top of the object window. Below the title bar, the toolbar lists the tool buttons associated with the Slide object.

NOTE: The Ctrl+Alt+Enter keyboard shortcut allows users to open a selected Sub-Object's properties. |
The display area appearing at the bottom of the Slide object window is used to enter and organize the text and images to be displayed at runtime. The display area is, itself, a SlideState object. By default, a new Slide object is created with a single SlideState object. Additional SlideState objects may be added. The Slide object is the parent to the collection of SlideState objects. In turn, a SlideState object is the parent to a collection of SlideStim objects, also called sub-objects, which are used to enter a single text, image, or sound stimulus. Combinations of sub-objects compose the structure of the SlideState. Multiple SlideState objects allow the customization of varying stimuli to be presented by the same parent object.
Refer to E-STUDIO: SlideState Object [22702] for a complete description of SlideState objects. Watch SlideState Creation for more information on how to create different SlideStates.
Refer to E-STUDIO: SlideButton Sub-Object [23598], E-STUDIO: SlideChoice Sub-Object [23599], E-STUDIO: SlideSlider Sub-Object [23600], and E-STUDIO: Slide Layout Template [23584] for more information on buttons.
Property Pages
The properties for the Slide object may be set using the Property pages. The Property pages may be displayed using the Property Pages tool button on the Slide object toolbar.
General Tab
The General tab displays the ActiveState, indicating the SlideState object to be displayed when the Run method is called for the parent object. The value for ActiveState may be the name of a specific SlideState, or may be an attribute reference, in order to vary the SlideState presentation (e.g., per condition). Additionally, optinons for the Display and Input Source are specified here.
| Property | Possible Values | Description |
| ActiveState | String values representing names of SlideState objects, Attribute references | Identifies the SlideState to be displayed when Run is called for the Slide object. |
| DisplayName |
Active Displays in the experiment |
Specifies which Display device the movie should be presented on (when using multiple monitors). |
| Input Source ACC | (input masks), SlideSliders, or SlideChoice sub-objects | Determines what component (i.e. input masks, SlideSlider, SlideChoice) the Slide ACC is derived from. |
| Input Source RT | (input masks), SlideSliders, or SlideChoice sub-objects | Determines what component (i.e. input masks, SlideSlider, SlideChoice) the Slide RT is derived from. |
| Input Source RESP | (input masks), SlideSliders, or SlideChoice sub-objects | Determines what component (i.e. input masks, SlideSlider, SlideChoice) the Slide RESP is derived from. |

Property Pages and Sub-Object Property Pages Buttons
The main difference between these two buttons in that the Property Pages button opens a Slide's properties. For example, this is where Duration and Input Masks are decided. The Sub-Objects Property Pages button opens a selected sub object's properties. Properties can be accessed for the sub-objects listed in the following article: E-STUDIO: Sub-Objects [22703]. For example, the Sub-Objects Property Pages button allows users to specify text on a SlideButton or a Filename of a SlideImage.
Both the Properties and Sub-Object Properties can be selected using the right click context menus.
