我使用這個自定義消息框,在MessageBox可以接收自定義字體,我正在尋找的方式,能夠通過調整用大字體大小niside默認的消息框窗口消息框窗口。
但是,如果我使用大尺寸字體,字體會顯示'truncated',那麼在調整窗口大小時,發現問題並不足以解決自定義字體大小問題。 ,我的意思是裁剪,即使如果我使用高分辨率調整消息框窗口大小,沒辦法,文本仍然會左上角,並顯示爲像在一個小框中裁剪。
所以我想我還需要調整包含在messagebox窗體內的文本消息或其他我完全錯過的控件,但這可能是調整大小?如何?
(這種習俗消息框是由Hans帕桑特編寫和修改了一點我:MessageBox with custom font?)

您已經在調用'MoveWindow',它可以做到這一點。將第4個和第5個參數更改爲所需的寬度和高度。 – endofzero
@endofzero謝謝你這麼多,但我發現一個問題,調整窗口大小不會解決字體大小的問題,字體將顯示'截斷',我的意思是裁剪,即使我使用高分辨率。那麼我需要在消息框窗口中調整大小以及如何操作? – ElektroStudios
