Setting checkstate on a ListWidgetItem


Setting checkstate on a ListWidgetItem

To fix the issue you can do I can't test this just now, but... I was under the impression that PyQt4 handled the screen updates automatically when items were checked/unchecked (at least, it does for QCheckBox items). It looks to me like your event handler is actually undoing the user's action. Have you tried commenting out the self.connect line and running again?
As I understand it, setCheckState() is really intended for setting the default state of each item...

How to convert int or bool to checkState

How to convert int or bool to checkState

I wish this helpful for you Consider CheckBox.Checked which is the boolean property. Use box.CheckState = (CheckState)ValueCheck; You can also use the ?: operator.
Update according to comments:
code :
CheckState ValueCheck;
private void....
this.gsCheck2.CheckState = (CheckState)ValueCheck;
CheckState cs = box.CheckState;
int ValueCheck = (int)cs;
string result = "Current state: " + ValueCheck + cs.ToString();

//You question:
MessageBox.Show(box.Name + (int)box.CheckState);
int result = box.CheckState == CheckState.Checked ? 1 : 0;
int result;
if (box.CheckState == CheckState.Checked)
    result = 1;
else
    result = 0;

this will help You need to use CheckState enumeration. So instead of string value "Indeterminate" use CheckState.Indeterminate etc.
Error on setting checkstate in a CheckedListBox control?

To fix the issue you can do for the advice. I guess the error was related the the fact that, under some circumstances, you cannot modify a set of controls during a For...Next loop.
I have revised my code and ended up with the following:
code :
Do While intCurrentItemIndex >= 0
    Dim strCurrentItem As String = clbOverviewColumnOrder.Items(intCurrentItemIndex)
    For Each col As DataGridViewColumn In frmTimingP2P.dgvOverview.Columns
        If col.HeaderText = strCurrentItem Then
            If col.Visible = True Then
                clbOverviewColumnOrder.SetItemCheckState(intCurrentItemIndex, CheckState.Checked)
            Else
                clbOverviewColumnOrder.SetItemCheckState(intCurrentItemIndex, CheckState.Unchecked)
            End If
        End If
    Next
    intCurrentItemIndex -= 1
Loop

hope this fix your issue first of all: QListWidgetItem does not have a clicked() signal. (It is not a widget itself) You should connect to QListWidget::itemClicked(QListWidgetItem*) - As you can see, this signal provides you the specific Item that has been clicked.
Of course, this alone won't help you, as the Item doesn't know the data displayed. You should store the information in the QListWidgetItem itself, using setData(), so you can get it later on from the Item.

like below fixes the issue The first argument to setData is the role number and for some reason you chose to set it to 1. The documentation says: "The data to be rendered as a decoration in the form of an icon. (QColor, QIcon or QPixmap)". So you are telling Qt to display an icon but you are not giving it a valid icon object.
Try setting the role to Qt::UserRole, which is "The first role that can be used for application-specific purposes." I am not sure how to access that constant from Ruby. If it is not provided by the qtruby gem, you could use 0x100 I suppose.
