7.2.2.2. Examples

We show you two different syntaxes for the dataController:

class GnrCustomWebPage(object):
    def main(self,root,**kwargs):
        bc = pane.borderContainer(height='200px')
        fb = bc.formbuilder(cols=2,datapath='test1')

        # First syntax
        fb.dataController("SET .aaa='positive number'" ,_if='shooter>=0',
                            _else="SET .aaa='negative number'",shooter='^.x')
        fb.numberTextbox(value='^.x',lbl='x')
        fb.textbox(value='^.aaa',margin='10px',lbl='aaa')

        # Second syntax
        fb.dataController("""if(shooter>=0){SET .bbb='positive number';}
                               else{SET .bbb='negative number';}""",
                               shooter='^.y')
        fb.numberTextbox(value='^.y',lbl='y')
        fb.textbox(value='^.bbb',margin='10px',lbl='bbb')
