界面布局
布局
- 將界面ui文件編譯為py文件
- 利用pyuic5工具進(jìn)行财岔，pyuic5 -o ui_xxx.py xxx.ui
- 編譯后的ui_xxx.py文件實(shí)際上是一個(gè)數(shù)據(jù)類
- 在該類里有創(chuàng)建窗口控件的代碼和控件的屬性配置數(shù)據(jù)
提升控件
- 現(xiàn)有的控件不足以表示注射泵的狀態(tài)
-
需要自定義控件时鸵，Qt提供了promote(提升)操作
image.png
image.png - 這樣就會(huì)有一個(gè)提升類Injector，這個(gè)控件就會(huì)是Injector的實(shí)例
- 在Python中實(shí)現(xiàn)這個(gè)類
資源
- 界面上需要用到一些圖片等資源
- 這些資源在QT中有專門的resource系統(tǒng)
- 創(chuàng)建一個(gè)qrc文件戈次，在文件中描述需要引用的資源
<RCC>
<qresource prefix="/res">
<file alias="v0">input.fw.png</file>
<file alias="v120">ManualPurge.fw.png</file>
<file alias="v240">output.fw.png</file>
<file alias="inj">planger.fw.png</file>
<file>megarobo.ico</file>
</qresource>
</RCC>
- 這個(gè)資源文件也需要被編譯為py數(shù)據(jù)文件
- pyrcc5 -o xxx.py xxx.qrc
- 對(duì)資源項(xiàng)目可以取個(gè)別名，便于在程序中通過狀態(tài)碼來得到資源數(shù)據(jù)
-
幾張圖片，分別表示注釋器和閥門的3種狀態(tài)趁餐，從而組合出注射泵的工作狀態(tài)
planger.fw.png
ManualPurge.fw.png
output.fw.png
input.fw.png
技術(shù)棧
- pyQt
- mega studio
引入包
- 系統(tǒng)包
- pyQt相關(guān)包
- injector模塊：自定義的注射泵狀態(tài)控件
- 界面模塊：利用QtDesigner設(shè)計(jì)的form
- 界面模塊需要利用pyuic5.exe進(jìn)行編譯散怖，轉(zhuǎn)換為py數(shù)據(jù)文件
- 資源模塊：
- 利用pyrcc5進(jìn)行編譯
- 資源中含有一些圖片和圖片的別名
- mrq.inj2
- 這是MEGAROBO對(duì)注射泵的Python封裝

事件驅(qū)動(dòng)
- 事件發(fā)生后菇绵，調(diào)用設(shè)備的相關(guān)方法進(jìn)行響應(yīng)
- 為按鈕添加消息處理函數(shù)
- 例如“閥門”切換到“吸入”狀態(tài)

漂亮一點(diǎn)
- 為界面添加風(fēng)格樣式

dat = fo.read()
fo.close()
app.setStyleSheet( dat )
添加風(fēng)格
