One part of that module creates a new font, for .net objects, such as Labels...\r\n\r\nIn my past approach (pythonnet 2.5.2; python 3.8) i had to use the following overload to perform this action\r\n\r\n`new_font = Font.Overloads[String, Single, FontStyle](font_type, font_size, font_style)`\r\n\r\nThe overload was needed, because in some combinations of the font_style, i got the following exception (for a combination that will trigger this exception, see the example at the end of the question):\r\n\r\n```\r\nnew_font = Font(font_type, font_size, int(font_style))\r\nSystem.ArgumentException: Ungültiger Parameter.\r\n   bei System.Drawing.Font.CreateNativeFont()\r\n\r\n   bei System.Drawing.Font.Initialize(FontFamily family, Single emSize, FontStyle style, GraphicsUnit unit, Byte gdiCharSet, Boolean gdiVerticalFont)\r\n\r\n   bei System.Drawing.Font..ctor(String familyName, Single emSize, GraphicsUnit unit)\r\n```\r\n\r\nSo far so good. If i use the same overload approach with pythonnet 3.0.1 and python 3.9, it wont work due the following exception.\r\n\r\n```\r\nnew_font = Font.Overloads[String, Single, FontStyle](font_type, font_size, font_style)     \r\nTypeError: No method matches given arguments for Font..ctor: (\u003cclass 'float'\u003e, \u003cclass 'System.Drawing.FontStyle'\u003e)\r\n```\r\n\r\nBut if i skip the overload, it seems to work now? So my questions is, which approach is the \"right one\" to implement a robust font setter with the current pythonnet version?\r\n\r\nFor better understanding, here a minimal example to reproduce my issue\r\n\r\n```\r\nimport clr\r\nclr.AddReference(\"System\")\r\nclr.AddReference(\"System.Drawing\")\r\nfrom System.Drawing import Font                         \r\nfrom System.Drawing import FontStyle                  \r\nfrom System import String     \r\nfrom System import Single\r\n\r\nfont_type = \"Arial\"\r\nfont_size = 12.0\r\nfont_style = FontStyle.Regular | FontStyle.Bold\r\n\r\n# fails with pythonnet 3.0.1; works with pythonnet 2.5.2\r\nnew_font = Font.Overloads[String, Single, FontStyle](font_type, font_size, font_style)     \r\n\r\n# works with pythonnet 3.0.1, but fails with pythonnet 2.5.2\r\nnew_font = Font(font_type, font_size, font_style)\r\n```\r\n\r\nI also created a question here in stackoverflow https://stackoverflow.com/questions/76668946/pythonnet-overloads-difference-between-v2-5-2-and-v3-0-1 (actually I copied my question and added it here)\r\n","author":{"url":"https://github.com/stranger0612","@type":"Person","name":"stranger0612"},"datePublished":"2023-07-20T05:32:58.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":10},"url":"https://github.com/2197/pythonnet/issues/2197"}
