Windows phone (19) learn more about TextBlock

 TextBlock

It is generally used to display Text elements. We usually use the Text attribute of this class. In fact, there are two ways to display Text. One is to set the internal Text, the other is to create a new Run object and LineBreak object in the Inlines set, which is called inline text]

The content of the Run label is the value of the Text attribute, which has some attributes of the TextBlock class, such as FontFamily, FontSize, FontStretch, and Foregroud;

New Line of LineBreak, line feed label

<Grid x: Name = "ContentPanel" Grid. Row = "1" Margin = "12,0, 12,0">
<TextBlock x: Name = "tbShow" Text = "Text Example" Foreground = "White" verticalignment = "Center" HorizontalAlignment = "Center">
<TextBlock. Inlines>
<Run Foreground = "Blue" Text = "ddd"> </Run>
</TextBlock. Inlines>
</TextBlock>
</Grid>

We can see the foreground and displayed text set in both the Run tag and the TextBlock tag, but what is the effect:

 

So we are sure that if the properties of the TextBlock label and the Run label defined in the TextBlock label are the same, the properties of the two are irrelevant, but the displayed Text set by Run is after the TextBlock attribute Text, if you want to run the program, the designer will directly see this error,

 

 

Let's take a look at the example below. We have listed some properties of the Run tag:

<! -- ContentPanel-place other content here -->
<Grid x: Name = "ContentPanel" Grid. Row = "1" Margin = "12,0, 12,0">
<TextBlock x: Name = "tbShow" Text = "Text Example" Foreground = "White" verticalignment = "Center" HorizontalAlignment = "Center">
<Run Foreground = "Blue"> Foreground Blue </Run> <LineBreak> </LineBreak>
<Run FontStyle = "Italic"> font style Italic </Run> <LineBreak> </LineBreak>
<Run FontSize = "30"> font 30 </Run> <LineBreak> </LineBreak>
<Run TextDecorations = "Underline"> Underline </Run> <LineBreak> </LineBreak>
<Run TextDecorations = "Underline"
FontSize = "30"
FontStyle = "Italic"
Foreground = "Blue"
Text = "Comprehensive"> </Run> <LineBreak> </LineBreak>
</TextBlock>
</Grid>

The result is as follows:

 

This section describes the inline Text of the Inlines set. This is a special usage of the TextBlock attribute Text.

 

Case code:

<! -- ContentPanel-place other content here -->
<Grid x: Name = "ContentPanel" Grid. Row = "1" Margin = "12,0, 12,0">
<TextBlock x: Name = "tbShow" Foreground = "White"
VerticalAlignment = "Center" HorizontalAlignment = "Center"
Text = "π indicates 3.14"
>
</TextBlock>
</Grid>

It achieves the following effects:

 

For example. End (.),
Enter,
Line feed. You can see that the format is similar. You can change the last letter or number to see what it is, for example

〇 is a circle. When using line breaks, we can set the TextBlock attribute TextWrapping = "Wrap", which indicates that when the display text exceeds the width limited by the container, text is automatically wrapped;

You can also set the text alignment mode. The TextAlignment attribute can be left, right, or center;

If you set the fontfamily attribute in textblock and the name is incorrect, the system will use the default font, however, if the font is obtained from a hidden file, the error font is still obtained;

MediaElement

 

 

It indicates the playing media. Currently, mp4, wma, mp3, and wmv are supported (ps: I just found a swf format not supported by Youku). The default AutoPlay attribute of MediaElement is True, therefore, when the video is buffered and can be played, the video will be automatically played.

The reference address sets the playback source. The xaml code is as follows:

<! -- ContentPanel-place other content here -->
<Grid x: Name = "ContentPanel" Background = "AntiqueWhite" Grid. Row = "1" Margin = "12,0, 12,0">

<MediaElement Source = "http://www.charlespetzold.com/Media/Walrus.wmv"> </MediaElement>
</Grid>

During playback:
