c++ - Qt set common background for all dialog boxes -


i working on developing qt 5 widgets desktop application want give common background windows , dialog boxes pop up. problem each window have specify same piece of code on , on again load same background. using paint function override not distort background when window resized. here's code:

settingsdialog::settingsdialog(qwidget *parent) :     qdialog(parent),     ui(new ui::settingsdialog) {     ui->setupui(this);     pixmapbg.load(":/images/google-material-design-wallpaper-10.jpg"); } void settingsdialog::paintevent(qpaintevent *pe) {         qpixmap pixmapbgl = pixmapbg.scaled(this->size());         qpalette palette;         palette.setbrush(qpalette::background, pixmapbgl);         this->setpalette(palette); }

is there way accommodate in qt using single file rather mentioning each window?

yes, can! have provide own stylesheet, or initialize application calling qapplication::setstylesheet(stylename).

follow comment: setstylesheet quickest approach, i.e.

qapp->setstylesheet("qdialog, qmessagebox {background-image: url(:/images/google-material-design-wallpaper-10.jpg);}");

assuming have valid qapplication reference qapp. note can refer custom subclasses well, if want refine scope of stylesheet.

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
