我使用自适应触发器使我的UWP应用程序的内容适合窗口大小。如果窗口小于1000px,则将堆叠所有三个矩形。如果不是,前两个矩形将并排,第三个将填充两个第一个矩形下方的整个窗口宽度。

<Rectangle Name="Rect2" Grid.Row="1" Grid.ColumnSpan="2" Grid.Column="0" Margin="10" Height="170" Fill="Green"/>
<Rectangle Grid.Row="2" Grid.ColumnSpan="2" Grid.Column="0" Height="400" Margin="10" Fill="Yellow"/>
</Grid>
</ScrollViewer>
但是,只有删除ScrollViewer
周围的Grid
后,自适应触发才有效。 HorizontalScrollMode
的{{1}}已被停用,但仍然无法正常工作:所有矩形都已堆叠,更改窗口宽度无效。
有没有办法让这个工作ScrollViewer
?
答案 0 :(得分:2)
你必须在XAML的第一个控件中设置setter,如果你将第一个Grid更改为ScrollViewer,你必须在Grid之前设置setter:
char*
strcpy(char *dst, const char *src)
{
char *s = dst;
while(*dst++ = *src++); // copy so long as there is
// '\0' found in src (including copying of that '\0')
return s;
}
