Configure the Multi-Touch settings for a specific project screen

Configure the Multi-Touch settings for a specific project screen when the project's default settings would not be appropriate.

Before you begin this task, you should have the selected Screen worksheet open for editing.

Keep in mind that the project's default settings are there to ensure that the project screens all behave the same way during project run time. Consistency makes your project easier to use. (For more information, see Configure the default Multi-Touch settings for all project screens.) As such, you should change the settings for a specific project screen only when it is absolutely necessary to the purpose of that screen.

To configure the Multi-Touch settings for a specific project screen:

1. Do one of the following:

   • On the Draw tab of the ribbon, in the Screen group, click Attributes; or

   • Right-click anywhere in the Screen worksheet, and then click Screen Attributes on the shortcut menu.

   The Screen Attributes dialog is displayed.

   

2. Click Multi-Touch Settings.

   The Multi-Touch Settings dialog is displayed, with most of the settings disabled because the screen is using the project's default settings.

3. Clear the Use Project Default option.

   

   The remaining settings are enabled for configuring.

4. In the Enable list, either click an option or type the name of a project tag (Boolean or Integer type).

   This setting determines whether the Multi-Touch features in general (that is, gestures, screen zoom/pan, inertia, touch events) are enabled for the selected screen style. If you typed the name of a project tag, the value of the tag will control the setting during project run time.

   Option	Description
   0:No	The Multi-Touch features are disabled for the selected screen style.
   1:Yes	The Multi-Touch features are enabled for the selected screen style.

5. In the Screen Zoom/Pan Gestures area, configure the zoom settings.

   1. In the Mode box, either select an option or type the name of a project tag (Integer type).

      This setting determines the zoom/pan mode for the selected screen style. If you type the name of a project tag, the value of that tag will determine the mode during project run time.

      Option	Description
      0:Disable	Zoom/Pan is disabled for the selected screen style.
      1:Inner	Inner Zoom/Pan is enabled for the selected screen style. Zooming changes the scale of the screen's contents, and panning moves the viewable area within the screen's border. The screen itself does not change size or position.
      2:Outer	Outer Zoom/Pan is enabled for the selected screen style. In practice, this is more like Resize/Move: zooming changes the size of the entire screen (automatically scaling the screen's contents to fit), and panning moves the screen in relation to the other open screens. Please note this mode is not directly supported on Mobile Access. However, selecting the Enable Screen View Zoom option (in the Mobile Access Configuration settings) produces essentially the same effect for all screens. For more information, see Configure the global settings for all areas.

      For more information, see Using multi-touch gestures in project screens.

   2. In the Max Inner Zoom (%) box, either select an option or type the name of a project tag (Integer type).

      This will be the maximum magnification allowed for the viewable area inside the project screen, when Mode is set to Inner. If you type the name of a project tag, the value of that tag will determine the zoom during project run time. Values less than 100 (that is, 100%) and greater than 1000 (that is, 1000%) will be ignored.

   3. In the Min Outer Zoom (%) box, either select an option or type the name of a project tag (Integer type).

      This will be the minimum size allowed for the project screen (as a percentage of size specified in the screen attributes), when Mode is set to Outer. If you type the name of a project tag, the value of that tag will determine the zoom during project run time. Values less than 20 (that is, 20%) and greater than 100 (that is, 100%) will be ignored.

   4. In the Max Outer Zoom (%) box, either select an option or type the name of a project tag (Integer type).

      This will be the maximum size allowed for the project screen (as a percentage of the size specified in the screen attributes), when Mode is set to Outer. The default option is (Auto), which means that the maximum screen size will be equal to the size of the display on which the project is viewed. If you type the name of a project tag, the value of that tag will determine the zoom during project run time. Values less than 100 (that is, 100%) and greater than 1000 (that is, 1000%) will be ignored.

6. In the Inertia Settings area, configure the deceleration values for the different types of movement.

   All values are in pixels per second.

   1. In the Deceleration box, either type a value or type the name of a project tag (Real type) that contains the value.

      This value controls the deceleration from "slide to pan" and "slide to move" gestures.

   2. In the Angular Deceleration box, either type a value or type the name of a project tag (Real type) that contains the value.

      This value controls the deceleration from "turn to rotate" gestures.

   3. In the Expansion Deceleration box, either type a value or type the name of a project tag (Real type) that contains the value.

      This value controls the deceleration from "pinch/stretch to resize" and "pinch/stretch to zoom" gestures.

7. Click OK to save the settings and close the dialog.
