## UI 教學
|
||||
### 1. 創建一個UI介面
|
||||
1. 在專案資料夾按下右鍵->External Tools->QtDesigner(此名稱會依據剛剛設定快速操作功能時名稱設定不同顯示不同)
|
||||
2. 跳出最右邊的畫面即可開始編制UI介面
|
||||

|
||||
|
||||
### 2. UI內部需注意之參數
|
||||
1. 選擇到物件時即可查看此元件能設定之參數
|
||||
2. 須注意objectName,python呼叫元件皆需要知道元件名稱,須清楚知道自己取了甚麼名稱
|
||||
|
||||

|
||||
|
||||
### 3. 儲存UI畫面
|
||||
1. 選擇到物件時即可查看此元件
|
||||
2. 儲存名字隨興後續程式呼叫名稱統一即可
|
||||

|
||||
|
||||
### *. 佈局
|
||||
畫面佈局使用Layouts與Spacers工具規劃,UI元件可動態變更大小
|
||||
