如何在Metro中计算字符串的宽度(不显示)
本文关键字:显示 字符串 Metro 计算 | 更新日期: 2023-09-27 18:22:25
我找不到与以下WPF代码等效的Windows Runtime来测量字符串的宽度:
FormattedText formattedText = new FormattedText(in_string,in_culture,in_flowdir,in_font,in_sz,in_color);
string_width = formattedText.WidthIncludingTrailingWhitespace);
有人知道在地铁里能不能做到吗?
有可能,我找到了一种可以提供有用测量的方法,但我不确定这是最好的方法:
// Setup the TextBlock with *everything* that affects how it
// will be drawn (this is not a complete example)
TextBlock^ tb = ref new TextBlock;
tb->VerticalAlignment = Windows::UI::Xaml::VerticalAlignment::Top;
tb->HorizontalAlignment = Windows::UI::Xaml::HorizontalAlignment::Left;
tb->Height = in_height;
tb->Text = text;
// Be sure to tell Measure() the correct dimensions that the TextBox
// have to draw in!
tb->Measure(SizeHelper::FromDimensions(Parent->Width,Parent->Height));
text_width = tb->DesiredSize.Width;
我的直觉是,在某些情况下,这段代码会产生意想不到的结果。
试试这个:
private double stringWidth(string s, double fontSize)
{
if(s==" ")
s = "'u00A0"; //this line wasn't required in silverlight but is now
TextBlock t = new TextBlock()
{
FontSize = fontSize,
Text = s
};
t.Measure(new Size(double.MaxValue, double.MaxValue)); //this line wasn't required in silverlight but is now
return t.ActualWidth;
}
