QUESTION

Setting node bounding box size in OGDF

Asked 2020-Nov-18 at 12:32

I'm attempting to layout and visualise a code flow graph in Qt using the OGDF library and the Sugiyama layout. The version I'm using is v2020.02, which should be the latest at the time of writing.

My issue: When creating nodes, I set them to various sizes, but after calling the SugiyamaLayout algorithm all node sizes are reset to 20x20 (presumably the default?). If I use another algorithm (such as PlanarizationLayout) instead, the issue disappears and node sizes keep their assigned values. I tried different configurations, such as rankings, crossMins and layouts, but the node size is not affected by those.

Minimal reproducible example:

After some more research, the OGDF Mailing List provided me with the answer.

This behavior is indeed caused by a bug in HierarchyLayoutModule.h, where the correct bounding box sizes aren't preserved.

The corresponding Github issue can be found here and will be fixed in the next release. In the meantime, it can be fixed by replacing the HierarchyLayoutModule::call method in \include\ogdf\layered\HierarchyLayoutModule.h with this code snippet:

I have a specific and a general problem I'm trying to solve.

Specific Problem: I want to create a new column in a data frame that gives a 1 if column C1 is 8 and all other values in the row are less than 8.How do I logically negate all of the other columns at the same time? Here is the code from my flawed attempt:

Asked 2017-Jul-19 at 02:12

I am trying to access a enum that is defined in a class of a library (ogdf) I use.

See line 65 here for the definition of the enum in the library.

If I try to access it like that (which I would think is the correct way):

Assuming that you're on the latest, it may be that the name of the enum changed and that documentation is old; looks like that documentation is from 2015, latest snapshots are (currently) from February 2017. From https://github.com/ogdf/ogdf/blob/master/include/ogdf/energybased/StressMinimization.h, the enum looks like this now:

QUESTION

C++ "Pure virtual method called" with use of abstract baseclass

Asked 2017-Jul-03 at 23:15

I am using a abstract baseclass with only pure virtual methods, to have a interface behavior (yes, I am coming from Java) in C++. As far as I did my research this seems to be the way to go.

I have to abstract base classes, GraphReader and Graph.

The problem is in Read function:

The instance of OgdfGraph og is local variable which is assigned to graph is returned from Read function. Please note that the variable og will go out of scope and deleted once Read function has executed. Hence graph will remain just a pointer to Graph* without any valid instance allocated to it.

You can fix it by changing OgdfGraph og as OgdfGraph* pog = new OgdfGraph()
