GWT / MVP: detect event changes in a table with the correct MVP pattern

Question

We are using gwt-presenter, but not really a question related to this ...

I have a table with users. When I create a table in the view (from the data provided by the presenter), I need to add two action buttons ("Change" and "Delete") at the end of the line.

What is the best way to assign click handlers to these buttons so that the presenter knows what has been pressed? Before that, we could transfer a private field from the presentation to the host and attach a separate click handler to this button. However, this method is pretty tough and doesn't work very well in this scenario.

Thanks in advance.

:

addRowEditClickHandler(ClickHandler handler) {
    this.rowEditClickHandler = handler; 
}
addRowDeleteClickHandler(ClickHandler handler) {
    this.rowDeleteClickHandler = handler; 
}

//... somewhere when setting up of the grid...

rowEditButton.addClickHandler = new ClickHandler() {
    onClick(args) {
        this.rowEditClickHandler.onClick(args)

}

rowDeleteButton.addClickHandler = new ClickHandler() {
    onClick(args) {
        this.rowDeleteClickHandler.onClick(args)

}

:

View view = new View();
view.addRowEditClickHandler( new ClickHandler() {
    onClick(args) {
        doSomething();
    }
});
view.addRowDeleteClickHandler( new ClickHandler() {
    onClick(args) {
        doSomething();
    }
});
