You can build a proxy model that does that, but none of the standard proxy models work that way. There is no standard functionality to do this. However, you can also use the view to do the work for you. Just set the correct modelIndex as the root index for the table view. If you want to display only children of the currently selected item in the tree view, you get that item's model index, map it to the corresponding index in the proxy (using one of the proxy model mapping methods), and set the resulting index as the root index for your table view.

I have a device which its display is with 180 degrees rotation. I run on this device QML application unside Qt QdeclarativeView. on my main.cpp i rotate the QDeclarativeView 180 degrees. Does this action affect the performance of my program (other QML paint operation will be slower) ?

I solved the problem by declaring @signals: void invalidEntry() const;@ it works OK

Ok, figured it out today by having a look at the designer source code. The designer converts the XML returned by QDesignerCustomWidgetInterface::domXml() into QDesignerCustomWidgetData by calling QDesignerCustomWidgetData::parseXml() The parseXml() method clearly states that one have to add the attribute displayname to the widget xml tag, for example: @<ui language="c++" displayname="My Custom Widget"> <widget class="..." ...> ... </widget> </ui>@ So long Daniel

Thanks Solved the issue.

I have just made a Driver update. from 285 to 301 on my NVidia 560 GTX. Still have those artefacts :(

@Mario: Thanks for the hint regarding QGraphicsTextItem. It might be a useful workaround, if nothing comes up that works for all QGraphicsItem subclasses.

I really appreciate it Andre! I followed your advice, changed some things around and now it's displaying. I can't say I'm 100% solid on stack/heap stuff and why it needed to be that way, but it gives me some reading to do. Thanks a ton!

Check the code that loads plugins in Qt Creator. I never checked what it does exactly, but since we have files defining dependencies and extra information like that it most likely does more than what the normal Qt methods for plugin loading does.

I have finally fixed my problem ! Just created a complete new project and copy pasted everything. I think it must have been something with a bad userfile? Thanks though !

Hmm.. It looks strange. AFAIK, this coe must work. But Chrome can't get x.backtrace also.

Setting a pen color with alpha and then drawing text works here perfectly...

Hi, ~TND5! Welcome to Qt Developer Network! As DerMan explained - any Qt top-level widgets without parents displays with QFrame. So if you run this code: @ QWidget a; // a - without parent a.setGeometry(10,10,300,200); // x = 10, y = 10, width = 300, height = 200 a.show(); // show it @ It will show new window which will contain all that a contains. But if you run this code in MainWindow for e.g: @ QWidget a(this); // a - with parent a.show(); // show it @ It will display a in this widget.

I revised the line to : glPolygonMode(GL_BACK, GL_LINE); the problem still exists, HHHOoooWWwwever, glPolygonMode(GL_FRONT, GL_LINE); sloved the problem and the two items come out to be as expected. Why?

I have resolved it, client missed CA certificate so: @Socket->addCaCertificates("C:/SOURCE/Project/Qt/server.csr");@ added to client fixed my problem.

@Lukas: Thank you for the links. I'm studying multithreading only to know its possibilities, and those links are just what I needed :-)

Well then a Hash is definetly the right thing and an encryption is definetly the wrong thing to use. Further one shouldn't make up own security/authorization protocols when not proficient in it. Your scheme looks like it's vulnerable to replay attacks (due to the determinism in "Server increments question").
