TaurusLauncherButton

class TaurusLauncherButton(parent=None, designMode=False, widget=None, icon=None, text=None)

Bases: PyQt4.QtGui.QPushButton, taurus.qt.qtgui.base.taurusbase.TaurusBaseWidget

This class provides a button that launches a modeless dialog containing a specified Taurus widget which gets the same model as the button. The button does not use the model directly. Instead it passes it to the associated widget.

Code examples:

# a button that launches a TaurusAttrForm when clicked
button =  TaurusLauncherButton(widget = TaurusAttrForm())
button.setModel('a/b/c') #a device name, which will be set at the TaurusAttrForm when clicking

# a button that launches a taurusLabel (whose model is an attribute: 'a/b/c/attrname')
button =  TaurusLauncherButton(widget = TaurusLabel())
button.setModel('a/b/c/attrname') # attr name, which will be set at the TaurusLabel when clicking

#same as the previous one, but using the parent model and putting a custom text and icon:
button =  TaurusLauncherButton(widget = TaurusLabel(), text='click me', icon='logos:taurus.png')
button.setUseParentModel(True)  #let's assume that the button's parent has a model of type "/a/b/c"
button.setModel('/attrname')
