我在Ubuntu 12.04上使用Python 2.7和wx。Wx Python圖像查看器 - atfer打開圖像文件菜單太緊
我用wx在Python中編寫了一個微小的圖像查看器。一切正常，但我的應用程序的主窗口的大小有問題。
當我打開一個普通大小的照片，我看到：
這是蠻好的。
但是當我打開另外一個文件，可以這樣說某事（一biiiiig圖的圖像）：
我的應用程序窗口中有一個錯誤的寬度，我的意思是看看菜單的太緊了，你甚至沒有看到一個「編輯」選項。
如何解決？我剛開始在Python WX，所以，請耐心等待:)

你期望什麼結果？你不明白你的'draw'方法的哪一部分？ – phineas
@phineas：當我打開一個尺寸非常大的圖像時，我會很喜歡這種圖像，我會看到滾動條或類似的圖像，以至於我可以看到我的整個應用程序gui，而不像我的第二個示例 – Katie
