Hi guys,
I'm still dealing with the flashing issue. To refresh everyone when
adding some data to a table a flashing starts on only some windows
computers and the problem goes away if a new profile is created. But it
can return and there does not seem to be an obvious cause.
The users are reporting that it happens after adding data to a grid.
The grid uses a dynamic DataSet - set to a method call to retrieve
data. In the method I retrieve data via a simple select statement. But
I have discovered the method to retrieve data is called in excess of 31
times (stop counting). Therefore, the grid.update() is being called a
lot - something is wrong.
I have every call to an "update()" enclosed in a dabo.ui.callAfter()
which is suppose to prevent multi-calls. So is there a way to determine
what (why) is the root cause of all the update() calls? Of course my
suspicion is there is a loop happening and that is root cause of the
flashing.
below is the code for the grid. Please note the update() method - is
that the wrong way to update the grid data?
class RestitutionLineItemGrid(dabo.ui.dGrid):
def afterInit(self):
super(dabo.ui.dGrid, self).afterInit()
#self.super()
self.RegID = 'res_grid_id'
self.HeaderFontBold = True
self.MovableColumns = True
#self.DataSource = self.Form.getGlTransData()
self.DataSet = self.Form.getGlTransData()
self.addColumn(Name="dateid", Order=10, DataField="gltrans_date",
DataType="string", Width=40, Caption="Date",
Sortable=True, Searchable=False, Editable=False,
HorizontalAlignment = 'Center')
col = dabo.ui.dColumn(self, Name="amount", Order=20,
DataField="gltrans_amount",
DataType="string", Caption="Amount Rec",
Sortable=False, Searchable=False,
Editable=True, Expand=False, HorizontalAlignment = 'Center')
...
def update(self):
try:
self.DataSet = self.Form.getGlTransData()
#super(dabo.ui.dGrid, self).update()
except:
pass
