Angular Material - prevent default on md-tab - angular-material

Question

I have a number of tabs, representing different services. I wish to have a final 'tab' tagged on the end of the list used to add a new service. Denoted by a simple '+'. This will open a simple dialogue.
I was hoping I could put my own ng-click behaviour on this single tab and prevent default but this doesn't work.
Is there any way I can 'catch' the tab click event BEFORE the tab body switch takes place and prevent it from happening?

Answer 1

It seems that it is not possible at the moment (see e.g. https://groups.google.com/forum/#!topic/ngmaterial/rNWMk3S9uDI) - at least using official api.
If you are ok with a solution which hacks into the directive internals then you can do following:
angular.module('MyApp').directive('tabWatcher', function() {
return {
require: ['mdTabs'],
restrict: 'A',
link: function(scope, el, attrs, controllers) {
var mdTabsCtrl = controllers[0];
var origSelectFn = mdTabsCtrl.select;
// overwrite original function with our own
mdTabsCtrl.select = function(index, canSkipClick) {
if (...) {
origSelectFn(index, canSkipClick);
}
}
}
};
I've placed a demo here http://codepen.io/jarek-jpa/pen/wGxqOq . Try to click some tabs. The select() call will be intercepted and depending on a condition let pass or not.
Disclaimer: Again, it hacks into the md-tabs directive internals, so may stop working any time (tested with angular-material 1.0.7)

Answer 2

You can set pointer-events to none to prevent the md-tab from responding to clicks.
Example:
<style>
md-tabs.readonly {
pointer-events: none;
user-select: none;
}
</style>
<md-tabs class="readonly">
<md-tab label="can't touch this"></md-tab>
</md-tabs>
This is tested to work with Angular Material 1.0.1
