Fixture definition presets

In fixture definitions, <Channel> and <Capability> elements can have a Preset attribute which specifies the type of the channel / capability to help QLC+ adapt e.g. the 3D Preview to the properties and peculiarities of each fixture.

See qlcchannel.h and qlccapability.h for a list of available presets and just search the repository for the name of a preset to see how and where it is used.

Capability presets can have parameters (resources), which are specified using the Res1 and Res2 attributes on the <Capability> element. The purpose and type is dependent on the preset, so look at other usages of the preset and at the presetType and presetUnits functions of qlccapability.cpp.

When adding / updating / removing a channel preset, do so in all of the following places:

• Fixture definition XSD schema
• Fixtures tool
• qlcchannel.h
• qlcchannel.cpp, both the setPreset and addPresetCapability functions
• All the places where it is used, i.e. fixtures and code; just search the repository for the preset name.

When adding / updating / removing a capability preset, do so in all of the following places:

• Fixture definition XSD schema
• qlccapability.h
• qlccapability.cpp, both the presetType and presetUnits functions (if the preset uses resources)
• All the places where it is used, i.e. fixtures and code; just search the repository for the preset name.

In both cases, you might want to open an issue at the Open Fixture Library repository to notify them about changes of the fixture definition format, so that the QLC+ export there can be adjusted.
