I managed to make some leeway however I am still having issues with it.
# Connections that I have set for my slider
self.ui.planeSizeHorizontalSlider.sliderPressed.connect(self.slider_pressed)
self.ui.planeSizeHorizontalSlider.sliderReleased.connect(self.
slider_released)
self.ui.planeSizeHorizontalSlider.valueChanged.connect(self.
plane_size_slider)
def slider_pressed(self):
cmds.undoInfo(openChunk=True, chunkName='SlideTest')
def slider_released(self):
cmds.undoInfo(closeChunk=True, chunkName='SlideTest')
def plane_size_slider(self, value):
img_plane_node = self.get_current_img_plane()
value /= 10.00
self.ui.planeSizeLineEdit.setText(str(value))
self.set_plane_size(img_plane_node, value)
def set_plane_size(self, node, value):
width = cmds.getAttr("{0}.width".format(node))
height = cmds.getAttr("{0}.height".format(node))
ratio = height / width
# This got regiters as additional actions...
cmds.setAttr("{0}.maintainRatio".format(node), 0)
cmds.setAttr("{0}.width".format(node), value)
cmds.setAttr("{0}.height".format(node), value * ratio)
cmds.setAttr("{0}.maintainRatio".format(node), 1)
However my undo queue is incorrect. Current queue stemming from the above
code (where the queue is empty to begin with) where I perform 2 slides...
# 1: #
# 2: #
# 3: #
# 4: #
# 5: SlideTest #
# 6: #
# 7: #
# 8: #
# 9: #
# 10: SlideTest #
Even so, when I do try to do an undo, it only works the first time and
nothing was changing thereafter. I presume the 'empty' entries are coming
from the `setAttr` in which I am expecting my undo queue to be something as
follows:
# 1: SlideTest #
# 2: SlideTest #
Appreciate in advance for any replies.
