Hello everyone, I have a little problem with the PySide QSlider. I'm trying
to draw text on the ticks of my QSlider. I saw that we could use
"sliderValueFromPosition" to find the position but impossible to make it
work correctly ... It always returns 0. I'll show you my code.
def __range_to_pos(self, value):
qt_options = QtGui.QStyleOptionSlider()
self.initStyleOption(qt_options)
style = QtGui.QApplication.style()
gr = style.subControlRect(style.CC_Slider, qt_options, style.
SC_SliderGroove, self)
sr = style.subControlRect(style.CC_Slider, qt_options, style.
SC_SliderHandle, self)
if self.orientation() == QtCore.Qt.Horizontal:
slider_length = sr.width()
slider_min = gr.x()
slider_max = gr.right() - slider_length + 1
else:
slider_length = sr.height()
slider_min = gr.y()
slider_max = gr.bottom() - slider_length + 1
return style.sliderValueFromPosition(
self.minimum(),
self.maximum(),
value,
slider_max - slider_min,
qt_options.upsideDown
)
I made an alternative but I have a small lag on my offset.
def __range_to_pos(self, value):
i_percent_interval = 100.0 / (self.maximum() - 1.0)
# Size from orientation
if self.orientation() == QtCore.Qt.Horizontal:
f_size = self.rect().width()
else:
f_size = self.rect().height()
# Calculate offset
qt_font_metric = QtGui.QPainter(self).fontMetrics()
f_text_size = float(qt_font_metric.width(str(value)))
i_percent_offset = (f_text_size / f_size) * 100.0
f_offset = f_size / 100.0 * i_percent_offset
if value == 0:
f_offset = 0.0
elif value != self.maximum() - 1:
f_offset /= 2.0
# Position
x_pos = f_size / 100.0 * (i_percent_interval * value)
if self.orientation() == QtCore.Qt.Horizontal:
qt_pos = QtCore.QPoint(x_pos - f_offset, self.rect().bottom())
else:
qt_pos = QtCore.QPoint(self.rect().bottom(), x_pos - f_offset)
return qt_pos
I find it a pity not to be able to operate the command of PySide. Does
anyone know the solution?
