Does anyone see an issue with adding jQuery to GwtHostPage? Some PatternFly widgets require bootstrap.min.js which requires jQuery.
My understanding is that PatternFly is essentially a "skin" of Bootstrap CSS, which doesn't imply the need for using Bootstrap _JavaScript_ library (which needs jQuery) to deal with widgets in JavaScript runtime. I thought that the purpose of "gwtbootstrap3" GWT module (integration with Bootstrap CSS framework) was to provide such widgets in context of GWT app. If not, what is then the purpose of "gwtbootstrap3" module? In other words, doesn't "gwtbootstrap3" module provide us with all widgets we need?
Thanks, Greg

I wouldn't say "provide." It enables using the widgets more easily from GWT. Take a look at https://github.com/gwtbootstrap3/gwtbootstrap3/blob/master/gwtbootstrap3/src... line 521 on down. It simply wraps everything for ease-of-use from GWT / UIBinder. Greg

I'm not sure this is the only way. gwtbootstrap3 could do the same thing, after all its code becomes JavaScript in the end. I think there is no real difference (conceptually) between bootstrap.js vs gwtbootstrap3, each one can use JavaScript to implement widgets like tooltips. In the end it boils down to styling DOM elements with CSS classes, so Bootstrap CSS framework is the lowest common denominator.
The only reason I didn't add them in the main PatternFly patch is that we didn't need them back then. But now we need them.
Hm, I assume you mean this: http://getbootstrap.com/javascript/#tooltips these are jQuery plugins, apparently bootstrap.js builds on top of jQuery to ease the work with DOM elements. For example: $('#example').tooltip(options) will register mouse listeners on given element that control the tooltip. Anyway, the tooltip behavior is just JavaScript + setting CSS classes, not really related to jQuery. However, I found this: https://github.com/gwtbootstrap3/gwtbootstrap3/blob/master/gwtbootstrap3/src... so it seems that gwtbootstrap3 _does_ support things like tooltips. EDIT: see my comment below, Tooltip.java depends on jQuery, you're right.

You are correct. So gwtbootstrap3 requires jQuery. I didn't know this, just realized this now after looking at Tooltip.java code. So gwtbootstrap3 is just a thin GWT wrapper to bootstrap.js which implies the need for jQuery. (Originally I thought it's not just a thin wrapper.) Considering above, I'm OK with adding jQuery to GWT UI host page. BTW, we could do this via <script> in GwtCommon.gwt.xml which will cause the script to be automatically injected into GWT compilation (permutation) output, so we wouldn't need to modify host page HTML. However, question is, how/where to maintain jQuery script file(s).

I have to RPM package gwtbootstrap3 and patternfly, so I'll just add it in one of those RPMs. Probably the patternfly one. It'll be an additional Source in the spec. Sound ok?

All public resources should be copied into final WAR output during GWT application build. This means we could use jquery-1.11.0.min.js bundled within gwtbootstrap3. What do you think?

Namespace collision -- no. jQuery registers itself globally as '$' and 'jQuery', and neither GWT itself nor our GWT code use those names anywhere. However, there can be behavior conflicts. I'm currently debugging a problem where tooltips aren't destroyed when grid refreshes happen. The jQuery widget doesn't 'know' that the GWT widget it's attached to was destroyed :(
- is jQuery expected to substantially affect performance / loading time on the client side or anything like that?
First-load time will be negligible and cached. Mass-use of bad selectors could decrease browser performance. I think we should very rarely use jQuery in oVirt. Usages of it should be very justifiable. Greg
