[FIXED] QTextEdit doesn't show horizontal scrollbar upon resizing

Issue

[SOLVED]I would like to set the size for a QTextEdit document (say 8.5 x 11 or 3 x 5). If the user shrinks the view, then the horizontal scroll bar should appear. I cannot find the settings to stop linewrap when the user shrinks the view. If I stop linewrap completely, then all page size settings are ignored.

    self.parent = parent

    #FixedWidth disables re-size - NO H-scrollbar will appear       
    #        self.setFixedWidth(500)

    #LineWrapMode sets a Maximum line width for wrap, yet
    #re-sizing the view wraps text before maximum - NO H-scrollbar appear      
    self.setLineWrapMode(QTextEdit.FixedColumnWidth)
    self.setLineWrapColumnOrWidth(80)

    #PageSize sets a Maximum for wrap (same as above) NO H-scrollbar
    #        pageSize = QSizeF()
    #        pageSize.setWidth(80)
    #        self.document().setPageSize(pageSize)

    #NoWrap disables all above code. H-bar will show, but line never wraps.
    #        self.setWordWrapMode(QTextOption.NoWrap)

    app = QApplication(sys.argv)
    myWidget = myTextEdit()

    myWidget.show()
    sys.exit(app.exec_())

Solution

Setting the linewrapmode to FixedPixelWidth actually does what you want, i.e. horizontal scrollbars appear and lines are wrapped at a fixed position. I don't know why FixedColumnWidth in your example (and also here) doesn't give a similar result.

Example:

from PySide import QtGui, QtCore

app = QtGui.QApplication([])
window = QtGui.QWidget()
layout = QtGui.QVBoxLayout(window)
edit = QtGui.QTextEdit('jfdh afdhgfkjg fdnvfh vklkfjvkflj lddkl ljklfjkl jvkldjfkvljfgvjldf ll dl dljvklj ljljlbl  llkb jbgl')
edit.setLineWrapColumnOrWidth(200)
edit.setLineWrapMode(QtGui.QTextEdit.FixedPixelWidth)
layout.addWidget(edit)
window.show()
app.exec_()
