c++ - Why can't I set my QDialog to have no sizeGrip? -

according qt4 docs qdialog's sizegrip disabled default, mine has 1 anyways. try running setsizegripenabled(false) , still have one. so, else must causing this, don't know what. if matters dialog box has no parent because i'm designing/testing it. don't see why should matter, mentioning in case reason. here's full code:

#include "qtgui" //#include "clposter.h"  void add_new_account() {     // check::make sure process destroyed when it's supposed     // todo::connect signals slots     //     // create dialog box add user account     qdialog *accountdialog = new qdialog();     accountdialog->setmodal(true);     accountdialog->setwindowtitle("add new account");     accountdialog->setsizegripenabled(false);      // create main layout     qvboxlayout *mainvbox = new qvboxlayout(accountdialog);      qlabel *accountnamelabel = new qlabel(accountdialog);     accountnamelabel->settext("account:");     qlineedit *accountname = new qlineedit(accountdialog);     accountname->setminimumwidth(250);     qlabel *accountpasslabel = new qlabel(accountdialog);     accountpasslabel->settext("password:");     qlineedit *accountpass = new qlineedit(accountdialog);     accountpass->setechomode(qlineedit::password);      // note::may want use standard dialog buttons instead     qpushbutton *okbutton = new qpushbutton("ok", accountdialog);     qpushbutton *cancelbutton = new qpushbutton("cancel", accountdialog);      // connect signals slots      // set layout     // check::should accountdialog parent these? warning cannot set     //        because accountdialog has layout, expected, want them     //        automatically deleted when accountdialog makes sense make parent.     qvboxlayout *labelsvbox = new qvboxlayout(accountdialog);     labelsvbox->addwidget(accountnamelabel);     labelsvbox->addwidget(accountpasslabel);      qvboxlayout *lineeditsvbox = new qvboxlayout(accountdialog);     lineeditsvbox->addwidget(accountname);     lineeditsvbox->addwidget(accountpass);      qhboxlayout *tophbox = new qhboxlayout(accountdialog);     tophbox->addlayout(labelsvbox);     tophbox->addlayout(lineeditsvbox);      qhboxlayout *buttonhbox = new qhboxlayout(accountdialog);     buttonhbox->addstretch();     buttonhbox->addwidget(okbutton);     buttonhbox->addwidget(cancelbutton);      mainvbox->addlayout(tophbox);     mainvbox->addlayout(buttonhbox);      accountdialog->setlayout(mainvbox);      // show dialog     accountdialog->exec(); }  int main(int argc, char *argv[]) {     qapplication app(argc, argv);     //clposter mainwin;     //mainwin.show();     add_new_account();      return app.exec(); }  

setting parent should not affect anything.

you can around setting dialog fixed size using setfixedsize(width, height);

however work around.
