單擊按鈕最小化PyQt5應用

Question

我找到了一些有關如何將pyqt小部件最小化到系統托盤的材料，但是我沒有找到需要的東西。

我想最小化按鈕單擊時的小部件，我不想覆蓋默認的關閉按鈕，當用戶單擊窗口邊框關閉時，它仍將關閉，但是當單擊我的按鈕時，它將最小化到系統托盤。

這是有可能的，因為所有示例都嘗試覆蓋默認事件。 我要附加的這段代碼是在qtDesigner中創建的，它只包含一個按鈕，有點像操場，我希望有人可以幫助，干杯。

Qt Designer創建了一個用於填充另一個窗口小部件的類，它不是窗口小部件，因此建議創建一個從適當的窗口小部件繼承並使用Ui_Form類進行填充的類。 有關更多信息，請閱讀以下內容：

• http://pyqt.sourceforge.net/Docs/PyQt5/designer.html

至此，您必須使用showMinimized()方法。
