Re: [Interest] QLIneEdit Bug still valid ?

You'd have to check to see if that does not block the emission of the signal then after the user edited the text. Does anyone know what the signal emission order _should_ be in case where a user edits the line edit, and the validator corrects that input?

The cause is QLineControl::fixup() (src/gui/widgets/qlinecontrol.cpp, line 387) --- it calls QLineControl::internalSetText() with only 2 parameters, omitting the one that controls emission of the textEdited() signal. And since that parameter defaults to 'true', you get what you get. On 07/16/2012 03:38 PM, R.

Yeah, I also recall it was working correctly when I used it last time... However, the example acts wrongly, but it somehow only happens when the validator is set. The attached example (w/o the validator) works correctly.

Re: [Interest] jpeg dependency fix on kubuntu 12.04
Huh? QtSDK or qtcreator are not ubuntu/debian packages. Maybe something else is affected by this dependency, but I'm not aware what. It would be great though if sudo apt-get install qtsdk would work out of the box, especially for Qt5. I wonder if anyone is working on that? This is perhaps more for the development list On 07/17/2012 07:08 AM, Joseph Crowell wrote: Might be better to list package dependency problems to the package mangers forums/mailing list at Canonical.

Re: [Interest] QTcpSocket from QTcpServer
Thanks for the answer, I've found the problem. I called a Qt Slots from outside my object from a non Qt-Thread (std. Linux thread). I've fixed the problem by call a function of my (Qt) instance which emits a signal that is connected to my slot. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
[Interest] Problem understanding QAbstractProxyModel::mapFromSource and displaying summary data from a model
Hi, I am writing an app in which I am wanting to display my data in a number of different ways. (Currently QT4.8 on linux, but will also run it on windows, if this is relevant!) As an example what I have is a set of tuples with two field, say Name and Hours I have this working with table view and am able to access and edit the data. What I want is a not editable view of the data which shows the total of all the Hours for each Name. I have used the QAbstractProxyModel class to do this. My problem is I do not know how to implement the mapTosource and mapFromSource functions as there is not a direct 1 to 1 correlation between indexes in the proxy model and indexes in the source model. The function definitions appear to assume that this is the case. I have done a basic implementation of these functions which returns a default QModelIndex. The part I have found which is not working is that that the summary or total view does not update when I change values in the other view.I have changed the emit in the setData function to cover the whole model. The summary view does update when it gets focus. Can someone please tell me if there is something better than the QAbstractProxyModel for me to use for this purpose and How is the mapFromSource function suppose to work when there is not a 1:1 mapping between the abstract model and the source model? Are there any samples of QAbstractProxyMode available? With thanks, Hugh ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest

Are there any samples of QAbstractProxyMode available? With thanks, Hugh Hi, I think QAbstractProxyModel only applies when there IS a direct mapping between the elements of each model, that maintains their identity. You need a model with an element for each group (or grouping level), that listens for the changes in the source model and adjusts the group's summary, then signals the change for that one group. The QML VisualDataModel component looks like it has grouping capabilities. Maybe you can get some ideas from its implementation? Hope that helps, Tony. ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
