Brief Description of the Algorithm

The Random Layout algorithm is not really a layout algorithm. It simply places the nodes at randomly computed positions inside a user-defined region. Nevertheless, the Random Layout algorithm may be useful when a random, initial placement is needed by another layout algorithm or in cases where an attractive, readable drawing is not important.


// ... IlvGrapher* grapher = new IlvGrapher(display); // ... Fill in here the grapher with nodes and links in IlvRandomLayout* layout = new IlvRandomLayout(); layout->attach(grapher); // Perform the layout IlvGraphLayoutReport* layoutReport = layout->performLayout(); if (layoutReport->getCode() != IlvLayoutReportLayoutDone) IlvWarning(“Layout not done. Error code = %d\n”, layoutReport->getCode()); // ... // If the grapher is not anymore subject of layout: layout->detach(); // Once the layout algorithm is not anymore needed: delete layout;
