The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

QLayout or mapToGlobal or setGeometry problem

Asked by Endelm in QT Programming Language, C++ Programming Language

Tags: C++, Qt 4.3

Hi

I have a QFrame and in the QFrame is a layout with 3 rows.
I want a slider to appear on Y exactly there where i clicked with the mouse.
Instead it always appears at the same place in the middle of the QFrame.
When moving the slider with the mouse (the actual slider not the handle) it works fine.
I use slider->setGeometry to move the slider.
I do the same in the createSlider function but something is wrong it does not appear at the place where i clicked. But somewhere in the middle.
Logging shows it should appear at the Y where i clicked. (when printing out y)

Also after I add this slider into the QFrame, it looks like another m_topDocker and m_bottomDocker appears under or over them,
is this a repaint problem? or a layout problem? im really confused...

THANK you in advanced.
