Make More Room for Title Bar Controls When Possible

[MichaelWDenney]

Calling this a new feature is a bit strong, but someone using our product raised the following suggestion/request:

The collapsing of the controls on the title bar seems to occur prematurely because an excessive amount of space is reserved after the title. This can be seen in both our application and the BasicCheckRibbon:

In both images, I have expanded the popup to show the hidden controls. There is more than sufficient room for those controls on the title bar, if the title was shifted further to the right. I believe the positioning of the title is currently controlled by the OS although how it interacts with the positioning of controls on the title bar, I'm not sure. I guess the context tab groups are also a consideration.

Of course, it is possible to go too far the other way and have the controls push the title all the way over or even cause the title to be concatenated. Maybe allow setting of a preferred title alignment and/or setting a title bar priority order?

It's indeed a balance between four things:

1. Title pane control decorations - application icon and close / minimize / maximize / restore buttons
2. Title text
3. Contextual task tabs location, which depends on how many regular tasks you have
4. Taskbar items

The first two can be configured via RadianceThemingCortex.GlobalScope.configureTitleContentGravity API for all the windows. You can mark the app icon to be at the edge or next to the title, and the buttons to be at one of the edges. The title can be configured to be either at the edge or centered.

The location of the contextual task tabs is not directly configured via an API call. It depends on how many regular tasks you have, and how wide each one of the task title is.

The last piece is the max task bar width given to it. Right now it is hardcoded to 25% of the overall window width. That seemed to me to strike a balance between showing a decent amount of pinned items, leaving enough room for the title, and preventing the title pane from being too cluttered overall.

The more space you give to the taskbar, the less space you'll have left for the title, especially if you have contextual tabs. Also, at some point the taskbar becomes too wide and start interfering with the leftmost contextual task tab.

I can see an argument to add an API at the JRibbon level to set the percentage ratio of the window width to be given to the taskbar, and leave it up to the app side to figure out how to balance these four items depending on the app-specific priorities between the title, the contextual task tabs and the taskbar. Anything beyond that would be too brittle to handle generically at the library level.
