This article shows you the specific operation methods of C++ to achieve WPF animation, the content is concise and easy to understand, absolutely can make your eyes bright, through the detailed introduction of this article, I hope you can get something.

C++ programming language should be in a wide range of ways, which can help us to easily achieve many functional requirements.

Many people are used to using Blend to help edit XAML files and generate a lot of animation. But in the actual development, using the code to achieve animation is still very practical, and the logic of the code development ability is stronger, easier to control, this aspect of C# examples have been many, the following I introduce a few C++ WPF animation examples.

First of all, I will introduce the gradual emergence of less and less, that is, Alpha Animation. The animation code for C++ to implement WPF is as follows

/ *

* Take Label for example

, /

/ / 1, Find the lable by its name, The name define in the xaml file

Label^ pColorLabel = (label^) page- > FindName ("ColorAnimationLabel")

/ / 2, Define a DoubleAnimation object

Double pDoubleAnimation ^ gcnew DoubleAnimation ()

/ / 3, Set from to and duration

PDoubleAnimation- > From = 1

PDoubleAnimation- > To = 0

PDoubleAnimation- > DurationDuration = Duration (TimeSpan::FromSeconds (3))

/ / 4, Create a storyboard (Timeline)

Storyboard ^ pStoryboard = gcnew Storyboard ()

/ / 5, Set the DoubleAnimation's target name

PStoryboard- > SetTargetName (pDoubleAnimation, _ T ("ColorAnimationLabel"))

/ / 6, Set the DoubleAnimation's property

PStoryboard- > SetTargetProperty (pDoubleAnimation

Gcnew PropertyPath (Label::OpacityProperty))

/ / 7, Add the DoubleAnimation object to the storyboard

PStoryboard- > Children- > Add (pDoubleAnimation)

/ / 8, Start the animation

PStoryboard- > Begin (pColorLabel)

The XAML used by C++ above to implement the WPF animation code is as follows

< Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >

< Grid>

< DockPanel>

< Button Name="ColorAnmationButton" Width="100" Height="50" Background="LightBlue">

Color Anmation

< /Button>

< Label Name="ColorAnimationLabel" Width="200" Height="50" Background="Red">

< /Label>

< /DockPanel>

< /Grid>

< /Page>
