467360 - support buttons with child panels

Status: RESOLVED FIXED

(Toolkit :: UI Widgets, defect)

Description

Attachment: implement this

There was a request by mano at one point to support putting panels inside buttons, as in:

<button id="button" type="panel" label="Button">
  <panel>
    <textbox/>
  </panel>
</button>

that would work just like type="menu".

Dao, an issue I found with this is that in this example:

<toolbarbutton id="button" type="panel" label="Button">
  <panel>
    <textbox/>
  </panel>
</toolbarbutton>

On Mac, the text-shadow defined on the toolbarbutton is messing up the textbox in the panel. Characters typed aren't being drawn correctly, instead they seem to be just a few pixels of garbage at the left edge of the textbox. Is there still an issue with text-shadow inheritance?

Sure that it's text-shadow and not something else? Should be easy to investigate this (at least, exclude text-shadow) using DOMi, e.g. by looking a the computed style, setting style="text-shadow:none" on the toolbarbutton, etc.

By the way, it's also a little strange that popups inherit text-shadow.

Actually, it seems more work may be necessary to support this. Another issue is that the button key event handling is also interfering.

I guess this works at least as well as <button type="menu"><menupopup ignorekeys="true"> ;-)
Anyway, I have no objection to it.

- changes the popup manager so that it keeps track of the popup type for menu opens, so that focus is cleared in FirePopupShowingEvent.
- disables button key navigation when a button's popup is open or is a popup type of menu.

Whats needed (aside from review) to get this patch in for 1.9.1? I'm playing with panels and it seems they solve at least some of my problems with popup-in-popups. I think since the text-shadow issue can be worked around quite easily, this bug should go in soon.

Comment 7

[Philipp Kewisch [:Fallen][📱📆]]

I also think all other elements that support menupopups should support panels.

OK, yes I think only the text shadow issue remains, which is bug 467817.

What other elements? The only other elements are all menu related and it doesn't make sense to support panels for them.

Just skimming this: I'm not sure these tests are correct, in particular the open test is incorrect for non-menu buttons and the type test isn't generic. My suggestions would be something like this:
if (this.boxObject instanceof Components.interfaces.nsIMenuBoxObject) {
  if (this.open)
    return;
} else {
  /* arrow key processing here */
}

I'd like to see this in 1.9.1, calendar could make use of this patch.

Phillip, can you explain what UI or feature would make use of this?

Comment 15

[Benjamin Smedberg]

Not blocking. Enn says he doesn't think we want this for 1.9.1, but wants to know why calendar wants/needs it.

From the point of view of just making XUL apps more capable on 1.9.1 I'd like to see this on branch.

Documentation for this should be added to:
