4 months ago Also see panel._original_content_height is updated after some frame . so please check it . properly . MDExpansionPanel need to be fixed . see i use Clock to get updated value panel._original_content_height. in Desktop it not needed but in mobile device it is needed . please see those things properly .
def tap_expansion_chevron(self,panel,content,header,chevron):
Animation(
padding=[0, dp(12), 0, dp(12)]
if not panel.is_open
else [0, 0, 0, 0],
d=0.2,
).start(panel)
print(panel._content)#=content
print(panel._header) #=header
print(panel._original_content_height)
#panel._header = ObjectProperty() # MDExpansionPanelHeader object
#_content =
#panel.open() if not panel.is_open else panel.close()
Clock.schedule_once(partial(self._call,panel))
def _call(self,panel,dt):
print(panel._content)#=content
print(panel._header) #=header
print(panel._original_content_height)
panel.open() if not panel.is_open else panel.close()
def _set_content_height(self, *args): self._original_content_height = self._content.height - dp(88) self._content.height = 0 IN THIS LINE self._original_content_height = self._content.height - dp(88) dp(88) subtraction is not required .
If we add widgets in MDExpansionPanelContent widget then there is some error for calculation and MDExpansionPanelContent's children not set in boxlayout properly ,
