#### 2021/11/28 主レイアウトの最小高をSubPanelに設定してみた
|
|
87
|
+
|
|
88
|
+
ウィジェットやレイアウトのSizeやHintSizeを表示してみて、やっぱりというかSubPanel（QPushButtonとQTableWidgetのまとめ役）の高さが妙な高さ（というか私がよく分かっていない）であるため、見た目が妙な間延びで表示されているところまでは分かりました。
|
|
89
|
+
|
|

|

解決方法は分かっていませんが、期待に一番近いのはSubPanelの主パネルが示してくれる最小高をSubPanelの高さに指定する方法です。
|
|
91

|
|
92
|

```c++
|
|
93
|
+
setFixedHeight(layout->totalMinimumSize().height());
|
|
94
|
+
```
|
|
95
|
+
|
|
96
|
+
これが最適解かどうかはわかりませんが、少なくとも見た目は期待通りになりました。
