size - QT - Resize QToolbar -

-

i have concatenate toolbar. every toolbar have call:

toolbar->setgeometry(x,y,width,height)

but have no resize.

i try call

toolbar->updategeometry();

but nothing.

my goal expand every toolbar size definition

there chance using repositioning toolbars on init , saving @ closing.

here solid way that:

what need use qmainwindow savegeometry() , restoregeometry() functions , save , load byte array through qsettings interface.

writesettings

qsettings s;  s.begingroup("mainwindow");  this->restoregeometry(s.value("geometry").tobytearray()); this->restorestate(s.value("windowstate").tobytearray());  s.endgroup();

readsettings

qsettings s;  s.begingroup("mainwindow");  s.setvalue("geometry", savegeometry()); s.setvalue("windowstate", savestate());  s.endgroup();

hope helps.

i'm trying give django-easy-pdf go, i'm having problems installing dependencies. i importerror: no module named xhtml2pdf.default when running django. to attempt fixing, did pip install xhtml2pdf , yields could not find downloads satisfy requirement pypdf (from xhtml2pdf) . so let's pip install --allow-unverified pypdf pypdf around that. completed without issues. when repeating pip install xhtml2pdf , software gets installed without issue. however, when launching django 1.6, get: importerror: reportlab version 2.1+ needed! . i have reportlab 2.2 or higher installed though, since pip freeze lists 3.0. it looks hardcoded in few files ( util.py , __init__.py ): if not (reportlab.version[0] == "2" , reportlab.version[2] >= "1"): raise importerror("reportlab version 2.1+ needed!") if not reportlab22: raise importerror, "reportlab toolkit version 2.2 or higher needed" how can fixed (except remove these c...

collision detection - C++ library for mesh to mesh intersection: what is available? -

-
i need calculate volume intersection , penetration depth between 3d triangular meshes (e.g. in .obj format), quite new computational geometry. in previous post ( mesh mesh intersections ) , google search, found few c++ libraries might appropriate job: cgal pqp libigl swift though, not sure 1 appropriate beginner. suggestion? libigl of version 1.1 has robust mesh boolean operations in igl/boolean/mesh_boolean.h . uses either implementation using cgal's exact arithmetic kernel or wrapper of cork (another option you). for now, libigl contains patched version of cork in libigl/external/cork , improves robustness. while implementing libigl's boolean ops, found cork faster not produce correct result (specifically, fails resolve intersections). libigl, using cgal backend, robust , still fast compared converting mesh cgal's nef_polyhedron , conducting csg operations , converting mesh. final conversion possible if result manifold. instead, libigl use...
