如何确定字符串的大小在wxWidgets中给出当前字体 [英] Howto determine the size of a string give the current font in wxWidgets

问题描述

是否有一种方法可以根据(C ++)wxWidgets中当前选择的字体来确定给定字符串的显示长度(以像素为单位)?

Is there a way to determine the display length of a given string (in pixels) based on the currently selected font in (C++) wxWidgets?

例如，如果我打印出字符串"Speed:"，并想在:"和将要跟随的值之间放置10个像素，那么我需要知道"Speed:"字符串有多长时间.有没有办法确定这一点?我似乎在API文档中找不到任何内容，但可能会丢失一些内容.

For example if I print out the string "Speed:" and want to put 10 pixels between the ':' and the value about to follow, I need to know how long the "Speed:" string was. Is there a way to determine this? I can't seem to find anything in the API documentation but I may be missing something.

推荐答案

也许 http://docs.wxwidgets.org/stable/wx_wxdc.html#wxdcgettextextent ?
