+MusE can create LADSPA GUI's (graphical user interfaces) from
+Qt designer *.ui files at runtime.
+This allows a user to create or modify customized LADSPA guis without
+recompiling MusE.
+
+======================
+ Installation
+=====================
+
+Copy the file muse/widgets/musewidgetsplugin.so into a directory were
+Qt (designer) can find it.
+
+Example:
+ if you installed Qt in /usr/qt3:
+ su -c "cp -af musewidgetsplugin.so /usr/qt3/plugins/designer"
+Check:
+ After starting the Qt designer you see all MusE specific widgets
+ under Tools/MusE. If you cannot find any MusE widgets, designer
+ did not find the file "musewidgetsplugin.so".
+
+======================
+ Environment
+======================
+
+Naming:
+ The Qt designer files are named after the LADSPA plugin ID.
+ Example: the "freeverb" plugin has the id "1050". 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" followed by the parameter
+index.
+ Example:
+ A "Slider" widget which manipulates the 3th parameter of a
+ plugin has the name "P3slider".
+
+Supported Widgets:
+ "Slider" slider for float values
+ "DoubleLabel" entry for float values
+ "QCheckbox" to manipulate a on/off LADSPA parameter
+ "QComboBox" select from a list of named values; sets
+ integer LADSPA values
+
+(for more hints please look at the example *.ui files)
