Notes

This is the first stable release of MahApps.Metro.

We removed everything marked as obsolete and made some API changes, but from now on MahApps.Metro follows Semantic Versioning, at least API wise. Please note that minor visual changes can still occur if there's a need for them.

Notes

We're nearly ready to release version 1.0 of MahApps.Metro, so this may be the last unstable release.

There are no known breaking changes in this release, but we had to deprecate some things, particularly around the titlebar overlay behavior.

Please note that everything that is know deprecated will be removed in the 1.0 release, so you should prepare your applications soon.

Since we're following semantic versioning, we promise to not break anything from version 1.0 to 2.0.

Features

MetroWindow now indicates whether it's active or not

The MetroWindow now has the NonActiveWindowTitleBrush property that sets the window brush for an inactive window.

See PR #1320

Fine grained control over the titlebar element overlay behavior

The overlay behavior of the elements of the window titlebar can now be controlled individually.

There are is now an enum with four values:

• Never
• OverlayFlyout
• OverlayHiddenTitleBar
• Always

For more info, see PR #1427.

Underlined TabControl

Added the attached property ControlsHelper.IsUnderlined="True" for the TabControl control that adds an underline.

See PR #1425 for reference.

Custom ScrollBar width and height

The default ScrollBar width and height can now be set manually.

See PR #1387for more infos.

Direct FlatButton style

Previously you had to include the FlatButton resource dictionary to add a FlatButton.
Now you can just set it at style of a button.

MetroWindow icon EdgeMode

It is now possible to set the EdgeMode of the window icon.

Changes

Notes

The 0.13 release of MahApps.Metro marks a very important change in the MetroWindow infrastructure along with several other fixes and improvements.

We've also updated the MahApps.Metro.Resources NuGet package with the latest icons.

Features

Custom themes

MahApps.Metro now allows to define custom themes for the application. We've rewritten the ThemeManager for this (don't worry, your old code should still work, but most old methods are now marked as Obsolete)

To add a theme, use the new AddAppTheme theme method.

Completely rewritten BorderlessWindowBehavior

The BorderlessWindowBehavior has been completely rewritten, to fix a number of issues that have accumulated over time.

For a complete list of fixes, see PR #1156

Auto-closing flyouts

Flyouts now have an option to be automatically closed when the user clicks outside of the flyout.
We renamed the property IsPinnable (that had no use) to IsPinned for this.
IsPinned is true by default and, if set to false, enables the auto-closing feature.

RangeSlider

The RangeSlider control has been completely rewritten because it was unusably broken before.

See PR #1055 for more info.

Titlebar enhancements

• The titlebar now supports vector icons
• Added LeftWindowCommands
  This means that the normal WindowCommands property is now obsolete and is called RightWindowCommands
• The minimize/maximize/close button can now be styled

Notes

This is a bugfix release. It will most likely be the only bugfix release till v0.13.

Fixes

• Fixed various bugs with the themed Flyouts (#947 #949):
  • A dark Flyout doesn't have dark window commands anymore
  • Only the topmost Flyout changes the WindowCommands, if it is closed, the WindowCommands adapt to the underlying Flyout
  • Theme changes are respected properly
• Flyouts respect the template margin #867 #974
• Fixed an OverflowException in the CleanWindowStyle #897 # 903
• Fixed various bugs for the NumericUpDown control: #952 #953
  • Fix for NumericUpDown exception raised when trying to enter a number in scientific notation
  • Fixed a problem with too early speedup
• Improved the performance for theme changes, they should now work instantly.
• Fixed an issue with the WindowCommands of a CleanWindow, they were white and therefore invisible when a BorderlessWindowBehavior was attached.

Notes

After only 2 months and nearly 300 commits, this is one of the feature-richest releases we've ever done.

This release, again, contains some breaking changes.
We try to break things now rather than later, when we release version 1.0 (which is hopefully soon).

A quick overview:

• ProgressIndicator is now removed, as it wasn't working as expected.
  Use MetroProgressBar with IsIndeterminate = True instead, which should give a much smoother experience.
• Like ProgressIndicator, MetroImage has been removed because it was broken.
  A better alternative is to use a simple Rectangle, as described here
• For the same reasons, the Panorama control has been removed.
  While we have no drop-in replacement for this control, if you really want it back,
  you can always submit a pull request with a better Panorama, but beware, it most likely needs a serious rewrite.

Upcoming changes:

• The RangeSlider control is currently being rewritten, so expect some breaking changes here.

Features

Dialog system

The dialog system has been overhauled for better extensibility.

The SimpleDialog class now allows to create a custom dialog.

ProgressDialog is a dialog that displays progress (duh!) inspired by Github for Windows.
InputDialog works like the MessageDialog but allows the user to input text.

For reference, see PR #785 , #860 and #901 .

Modal Flyouts

Just like modal dialogs, Flyouts can now be made modal by setting the IsModal = true.
Thanks @grokys for this feature!

For reference, see PR #824

Themed Flyouts

A Flyout can now have a theme, just like MetroWindow

There are four different theme states, indicated by the FlyoutTheme enum:

• FlyoutTheme.Adapt: The flyout will use the theme if the host window
• FlyoutTheme.Inverse: The flyout will use the inverse theme of the host window
• FlyoutTheme.Dark: Always dark. This is the default value
• FlyoutTheme.Light: Always use the light theme
• FlyoutTheme.Accent: Instead of the dark/light theme, use the accent of the host window

This behavior can be set through the Theme property

Notes

Warning: This release has a few breaking changes.
A quick overview:

• 'Colours' -> 'Colors'
  For consistency, we've chosen to rename all occurendes of 'Colours' to 'Colors'
• The 'TransitioningContentControl' use now an enumeration for 'Transition'

More details here: https://github.com/MahApps/MahApps.Metro/wiki/Breaking-Changes-or-WTF-is-happening-with-the-ALPHA-version

Other things:

• You can now put all the resource dictionaries in your 'App.xaml' file
• ProgressIndicator is marked as 'Obsolete'. In future, use 'MetroProgressbar' with 'Indeterminate' set to 'true'
• Like the ProgressIndicator, the Panorama will be removed in future versions.
  There is a chance that it will be rewritten and reintroduced later on.
• TextBox, PasswordBox, ComboBox and DatePicker use now the Validation.ErrorTemplate for displaying errors.
  The default template is ValidationErrorTemplate.
• The Demo application has been completely rewritten.
