Question

我设法使一个程序合并在一起，该程序在多行上接收一个字符串并将它们打印到透明背景上。我想知道如果有颜色的字符串不同颜色的各个部分的一种方式。我知道有，但是我对win32的缺乏了解确实在这里困扰我。我需要将文本分成两部分并调用drawText（）还是可以在字符串的一半位置更改文本颜色？关于信息或解决方案的任何观点都是很好的。

示例：string =“用户名：用户已发送的某些消息。”

我已经在Stack和其他多个网站上进行搜索，但到目前为止还没有高兴。我通常不会，但是我已经转储了代码，因为它可以运行，您可以明白我的意思了。

由于缺少注释和代码状态，我向您致歉。

可能会有一些缩进，这不是程序中的情况，只是我必须在每行文本上按空格键4次。

是的，在调用DrawText之前必须使用DT_CALCRECT更改颜色

您使用DrawText选项正确调用了DrawText。这不会画任何东西，它只是计算矩形的高度（基于宽度...）。Python的DT_CALCRECT将为计算出的矩形返回一个元组。

然后再次使用相同的文本格式（没有if message == win32con.WM_PAINT: hDC, paintStruct = win32gui.BeginPaint(hWnd) fontSize = 16 lf = win32gui.LOGFONT() lf.lfFaceName = "Stencil" lf.lfHeight = fontSize lf.lfWeight = 600 lf.lfQuality = win32con.NONANTIALIASED_QUALITY hf = win32gui.CreateFontIndirect(lf) win32gui.SelectObject(hDC, hf) text1 = 'line1' text2 = 'line2' text3 = 'line3' rect = win32gui.GetClientRect(hWnd) textformat = win32con.DT_LEFT | win32con.DT_TOP win32gui.SetTextColor(hDC,win32api.RGB(255,0,0)) drawrect = win32gui.DrawText(hDC, text1, -1, rect, textformat | win32con.DT_CALCRECT); win32gui.DrawText(hDC, text1, -1, rect, textformat) l = drawrect[1][0] t = drawrect[1][1] r = drawrect[1][2] b = drawrect[1][3] height = b - t rect = (l, t + height, r, b + height) win32gui.SetTextColor(hDC,win32api.RGB(0,255,0)) drawrect = win32gui.DrawText(hDC, text2, -1, rect, textformat | win32con.DT_CALCRECT); win32gui.DrawText(hDC, text2, -1, rect, textformat) l = drawrect[1][0] t = drawrect[1][1] r = drawrect[1][2] b = drawrect[1][3] height = b - t rect = (l, t + height, r, b + height) win32gui.SetTextColor(hDC,win32api.RGB(0,0,255)) drawrect = win32gui.DrawText(hDC, text3, -1, rect, textformat | win32con.DT_CALCRECT); win32gui.DrawText(hDC, text3, -1, rect, textformat) win32gui.EndPaint(hWnd, paintStruct) return 0标志）调用state = { social_media: [], page_home: [], loading: true, }; getCoffee() { return new Promise(resolve => { setTimeout(() => resolve('☕'), 2000); // it takes half of a second to make coffee }); } async showData() { try { const wpSocial = axios(`${ACF_DATA_URL}/options/social_media_data`); const wpHome = axios(`${WP_DATA_URL}/pages?slug=home`); await this.getCoffee(); await Promise.all([wpSocial, wpHome]).then(response => { this.setState({ social_media: response[0].data.social_media_data, page_home: response[1].data[0], loading: false, }); }); } catch (e) { console.error(e); // } } componentDidMount() { this.showData(); }。然后偏移矩形，更改颜色，然后绘制下一个文本。

请注意，这在pywin32中会变得非常混乱，首先在C / C ++中进行尝试可能会更容易。
