sql - Problem with QSqlTableModel -- no automatic updates -

-

After setting up the table model in QT 4.4: 

  QSqlTableModel * sqlmodel = new QSqlTableModel (); Sqlmodel- & gt; Settable ("name"); Sqlmodel- & gt; SetEditStrategy (QSqlTableModel :: OnFieldChange); Sqlmodel- & gt; Selection (); Sqlmodel- & gt; RemoveColumn (0); TableView-> SetModel (sqlmodel); TableView-> Show ();

The content is displayed properly, but editing is not possible, error: 

  QSqlQuery :: value: is not located on a valid record

I can confirm that the bug is actually ok as you report it to 4.5.1 Documentation, such as, still gives an incorrect example (i.e., deleted columns calls).

Around the one hand I before the update sign, which is incorrect with QSqlRecord, which can be updated in DB and possibly fixing the idea of ​​fixing it. Along, but I can not get it to work - a call for the methods of that record parameter is crashing my toy-app with a BusError.

So I left that idea and there is no doubt what is the correct way to do it (visibility should be determined by the scene, not by model, right? -): Delete column and call tableView-> setColumnHidden (0, true) in return. In this way the ID ID is hidden and everything works.

So I think we can confirm that there is a documentation error and it opens an issue in Qt Tracker about it, so it can be fixed in the next documents, right?

-
I am evaluating the Asp.Net MVC framework for my enterprise application for the past few weeks. The one thing I'm trying to achieve is the master-detail view. As it is very clear that there is no vivestate and there is no postback. For example, now I am using the product, customer, order and order details table from the Northwind database and I am using the especial MVC. I want to make master-detail view. Basically I do not have to have separate ideas (pages of other words) for order and order details. View order and order details should be included. How should I design my controller and see how to get this functionality. Thanks & amp; Regards, Burhanuddin Ghee You want to write a domain-specific view-model class Adds an order and details from its order (I'm assuming that order-> order details are 1-> n relation, not familiar with Northwind): public class command view model (Public order order); Set;} public inenemable & lt; Order deletate & gt; ...

delphi - Mouseover hint for TChart series value -

-
I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query: chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End; Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar. Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...? This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you: Process TForm...
