我正在使用<TextView
android:id="@+id/lblDlgLogoutMessage"
style="@style/Details"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="32dp"
android:layout_marginEnd="16dp"
android:layout_marginBottom="32dp"
android:fitsSystemWindows="true"
android:gravity="center_horizontal"
android:text="@string/logout_msg"
android:textColor="@color/black"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/lblDlgLogoutTitle" />
,并尝试恢复添加到给定图中的pyqtgraph
类对象的属性。
尽管看起来这是一个简单的任务,但我不知道如何提取它,而documentation并没有太大帮助。
这是一个片段:
TextItem
我猜对了.x()和.y()并使其正确,但是了解如何提取其他特征也很重要!在当前形式下,它会引发:
import sys
from PyQt5.QtWidgets import QApplication, QWidget
import pyqtgraph as pg
import numpy as np
def refreshScreen(AnnotationsList):
for i in range(len(AnnotationsList)):
c = AnnotationsList[i]
# Now I need to extract information from the annotations:
x = c.x()
print(x)
y = c.y()
print(y)
text = c.text()
print(text)
OtherProperties = c.getProperty()
print(OtherProperties)
if __name__ == '__main__':
app = QApplication(sys.argv)
w = QWidget()
w.resize(250, 150)
w.move(300, 300)
w.setWindowTitle('Simple')
w.show()
AnnotationsList = []
c = pg.TextItem(anchor=(0,0), border=pg.mkPen(200, 200, 200))
c.setText(text='my_annotation', color=(0,0,0))
# coordinates for annotation
x = 5
y = 10
c.setPos(x,y)
AnnotationsList = np.append(AnnotationsList, c)
refreshScreen(AnnotationsList)
sys.exit(app.exec_())
答案 0 :(得分:0)
如果您选中source code,则会看到TextItem有一个QGraphicsTextItem存储信息,因此,如果要获取文本信息,应使用该对象:
text = c.textItem.toPlainText()
print(text)
