Configure the default Multi-Touch settings for all project screens

Configure the default Multi-Touch settings for all project screens in your project, so that the screens all behave the same way during project run time.

The Multi-Touch settings come preconfigured for most common uses, so you need to configure them further only if:

• You are not satisfied with the runtime behavior of these settings; and/or

• You want to use project tags to programmatically change the setting during project run time.

Keep in mind that these are the default settings for all screens in your project. If you only want to configure the settings for a specific screen, see Configure the Multi-Touch settings for a specific project screen.

To configure the default Multi-Touch settings for all project screens:

1. On the Project tab of the ribbon, in the Settings group, click Viewer.

   The Project Settings dialog is displayed with the Viewer tab selected.

   

2. Click Multi-Touch Settings.

   The Multi-Touch Settings dialog is displayed.

   

3. In the Screen Style list, click the style for which you want to configure the default settings.

   Every style has its own settings, so you might need to repeat the following steps for each style. For more information about the different styles of project screens, see Screen Attributes.

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.

   For a detailed explanation of how inertia is used in multi-touch gestures, see "Inertia Mechanics" at the Microsoft Developer Network website: https://docs.microsoft.com/en-us/windows/win32/wintouch/inertia-mechanics

7. Repeat from Step 3 for each style of screen that you want to configure.

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