I'm not experienced with javascript at all so bear with me. I'm trying to
make a Web Interface with many buttons, check boxes, selection lists, etc.
and associate with these widgets a set of data. So that changing the
selections on the interface update the data set.
Using qooxdoo, I made a class to hold the data, and added member functions
that will update the data set, based on passed variables. I then created an
interface window with all the widgets. What I want to do is associate the
member functions of the data set with listeners of the corresponding
widgets. My simple brain would like to do the following:
In window interface class:
* ...
mycheckboxgroup.addListener("changeSelection",
myDataSet.updateFunction(data_name,mycheckboxgroup), myDataSet);
...*
Then in data set class:
* ...
updateFunction : function(data_name,checkbox)
{
value = checkbox.getSelected().getValue();
this.setData(data_name,value);
}
...*
This implimentation just executes the updateFunction once as the listener is
added. Based on what I've read, this is because the function argument
should be a pointer to a function rather than a function() call. But then
how do you pass arguments to the Listener as it is constructed?
Is there a way to create a generic listener function that takes variable
arguments? I don't want to have to write the code for each new listener
function for each of the 50 checkboxgroups i have, but I want to add a
listner to each and associate that listener to a data set based on a
variable.
