Python...MouseClick in ListBox

[kiloran]

I'm looking at creating dialogs using Python, and I'm struggling to work out how to handle a mouseclick event.

Here's a stripped-to-basics version of my code:

Code: Select all   Expand viewCollapse view

# example of creating a dialog using Python
import uno
from com.sun.star.awt.PosSize import POSSIZE

def addAwtModel(oDM,srv,sName,dProps):
   oCM = oDM.createInstance("com.sun.star.awt.UnoControl"+ srv +"Model")
   while dProps:
      prp = dProps.popitem()
      uno.invoke(oCM,"setPropertyValue",(prp[0],prp[1]))
      oCM.Name = sName
   oDM.insertByName(sName,oCM)
   
def addShareDlg():
   ctx = uno.getComponentContext()
   smgr = ctx.ServiceManager
   oDM = smgr.createInstance("com.sun.star.awt.UnoControlDialogModel")
   oDM.Title = 'Test'
   
   oDialog = smgr.createInstance("com.sun.star.awt.UnoControlDialog")
   oDialog.setModel(oDM)
   
   addAwtModel(oDM,'ListBox','myListBox',{})
   listText = oDialog.getControl('myListBox')
   listText.addItem('aaa',1)
   listText.addItem('bbb',2)
   listText.setPosSize(10,10,400,300, POSSIZE)    # x, y, width, height, flag
   
   oDialog.setPosSize(20,0,500,500,POSSIZE)
   oDialog.setVisible(True)
   x = oDialog.execute()


I want to execute some code when I click on an element in the ListBox.
Can someone please point me in the right direction? Many thanks.

not sure about the difference between ActionListener and ItemListener. Check this out.

I found some code which implements a listener. It adds a count to a label when a button is clicked.

I then tried adding a ListBox and attached the same listener code to the ListBox.
This essentially works and would form the basis of what I want to do. HOWEVER.... I don't understand why I only need to click once on the button to increment the count, but I need to double-click on an item in the ListBox to achieve the same thing. I would prefer a single-click on the ListBox.

Can anyone provide any guidance
