Version: 1.0 (using KDE 3.0.9) Compiler: gcc version 3.2 OS: Linux (i686) release 2.4.19-gentoo-r9 I cant use the mouse to modify objects in any of the viewports, the mouse works fine for the rest of the application and in KDE. Running Gentoo 1.4, KDE 3.1 RC2, USB Mouse using the HID driver, and the nVidia kernel drivers.
Subject: Re: New: Viewports wont grab mouse Hi! What qt version do you use? Does the control point selection work? Do the cursor and the status bar change when the mouse is over a control point?
Subject: Re: Viewports wont grab mouse Hello, Sorry for the delay, I was away from a computer all weekend :) I am using qt-3.1.0_pre20021104. The cursor and status bar do not change when the mouse is over a control point. If I right click in one of the viewports and select Translate Views or Scale Views the mouse cursor changes and I can scale or translate the view. Let me know if you need any more information.

Subject: Re: Viewports wont grab mouse An object that has a transformation as child that is not invertable (like a scale <1,0,1>) can't be modified with the control points. Could this be the reason or are you not able to change _any_ objects with the control points?
Subject: Re: Viewports wont grab mouse I dont think so. For instance, if I create a blank scene and create a sphere from the toolbar, I get a sphere with three children if I highlight one of the children I do not see any control points on the sphere, but if I highlight the sphere in the hierarchy I see three control points, one on the X, Y, and Z axis, when I manuver the mouse over any of these points nothing happens. I can right click on the spere and select one of the control points from the menu, but I still cannot manipulate that with the mouse. To me this does not seem like the correct behavior.

Subject: Re: Viewports wont grab mouse 1) Do transformations work? Select the translation child and try to move the object around. 2) Remove all transformations select the sphere and try to drag the control points. Thanks for your help
Subject: Re: Viewports wont grab mouse 1) No 2) No No problem, thanks for yours :) Dave On Monday 11 November 2002 11:10 am, you wrote: > ------- You are receiving this mail because: ------- > You reported the bug, or are watching the reporter. > > http://bugs.kde.org/show_bug.cgi?id=50441 > > > > > ------- Additional Comments From zehender@kde.org 2002-11-11 20:10 ------- > Subject: Re: Viewports wont grab mouse > > 1) Do transformations work?

Subject: Debug session summary For the bug system a summary of our debug session - The control points can't be modified because the inverse matrix of the view transformation can't be build - PMMatrix::canBuildInverse( ) returns allways false - PMMatrix::det( ) returns allways 0 - In PMMatrix::notNullElementRow (which should find the row with the greatest value in a column) - The fabs( ) call in PMMatrix::notNullElementRow returns allways 0 - We removed the fabs call. The determinat was calculated correctly, but the fabs call in PMMatrix::canBuildInverse( ) (inside approxZero( )) failed and returned 0 Summary: Something with the fabs function is bugged. A small sample program returned the correct fabs result. Maybe more than one library contains this function and another one is used in the sample program. I will change the status to WorksForMe
See my last comment. No KPovModeler bug
