A gui for +            freeverb has to be named "1050.ui". +      The plugin ID is shown in the MusE plugin browser. + +Path: +      MusE looks for *ui files at (museglobalshare)/plugins/. +      If you installed MusE at "/usr" (configured with --prefix=/usr) +      MusE looks at "/usr/share/muse/plugins" for *ui files. + +====================== +   Creating *.ui file +====================== + +The association between LADSPA plugin parameters and Qt-Widgets is +done by name. All input widgets which manipulate a LADSPA parameter +must have a name starting with the letter "P". +The "id" property of every widget must be set to the parameter index +of the plugin, +One parameter can be manipulated with more than one widgets. + +      Example: +      A "Slider" widget which manipulates the 3th parameter of a +      plugin has the name "Pslider" and the "id" property has a +      value of "3". + +Supported Widgets: +      "AwlSlider"       slider for float values +      "AwlFloatEntry"   entry for float values +      "AwlCheckbox"     to manipulate a on/off LADSPA parameter +      "AwlComboBox"     select from a list of named values; sets +                        integer LADSPA values + +(for more hints please look at the example *.ui files) +  |
