Scaling Front Panel Objects (PDA Module, Touch Panel Module)
PDA and Touch Panel devices have different size screens than desktop PCs. Also, different PDA and Touch Panel devices might have different size screens. You can change the scale factor to accommodate different screen sizes.
Scaling has the following implications in LabVIEW:
- When you build a VI into a PDA or Touch Panel application using the default scale factor, LabVIEW reduces the user interface by a scale of two. If you change the scale factor in the build specification, LabVIEW scales the front panel controls and indicators when you build a VI into a PDA or Touch Panel application, .
- When you right-click a block diagram terminal and select Create»Control or Create»Indicator from the shortcut menu, LabVIEW adds a control or indicator to the front panel window in the size and style for the current target. For example, if the current target is a PDA or Touch Panel target, controls you create from a block diagram terminal are two times the size of a control or indicator you create when the target is Windows.
- LabVIEW does not scale bitmap images when you build the VI into a PDA or Touch Panel application. The bitmaps retain their original size to avoid the aliasing effects that can result if the bitmaps are reduced in size. You can select if the PDA Module or the Touch Panel Module generates 8-, 16-, and 24-bit bitmaps when you create the build specification.
PDA Module The PDA Module includes templates with the minimum window size for the Windows Mobile platform.
Touch Panel Module The Touch Panel Module includes templates with the minimum window size for the Windows CE platform.
