GenericInterfaceLayout.cpp

Parts of the GenericInterfaceLayout program are based on the SingleCapture.cpp example concerning the single snap of an image. The sample shows all GenICam™ interface properties which can be modified.

Program location

The source file GenericInterfaceLayout.cpp can be found under:

%INSTALLDIR%GenericInterfaceLayout

Note

If you have installed the package without example applications, this file will not be available. On Windows® the sample application can be installed or removed from the target system at any time by simply restarting the installation package.

GenericInterfaceLayout example:

1. Opens a Balluff device.
2. Afterwards, there are different possibilities, e.g. to snap an image, to list and change properties, etc.

Console Output

How it works

After getting the device from user input the sample shows on Windows® system a image display (mvIMPACT::acquire::display) at the same time the sample offeres several possibilities.

1. With list, device properties will be listed via a StringPropMap container. After the properties have been listed, you can set the properties.
2. With snap, the sample will snap one image from the device and updates the image display.

StringPropMap propertyMap;
DeviceComponentLocator locator( pDev, dltSetting, "Base" );
populatePropertyMap( propertyMap, Component( locator.searchbase_id() ).firstChild() );
locator = DeviceComponentLocator( pDev, dltRequest );
populatePropertyMap( propertyMap, Component( locator.searchbase_id() ).firstChild() );
locator = DeviceComponentLocator( pDev, dltSystemSettings );
populatePropertyMap( propertyMap, Component( locator.searchbase_id() ).firstChild(), string( "SystemSettings" ) );
locator = DeviceComponentLocator( pDev, dltInfo );
populatePropertyMap( propertyMap, Component( locator.searchbase_id() ).firstChild(), string( "Info" ) );
populatePropertyMap( propertyMap, Component( pDev->hDev() ).firstChild(), string( "Device" ) );

populatePropertyMap creates the path and shows the possible settings for each property.
