c++ - Putting a line on a QPushButton -

i creating program draws graphs; want able have button user can press choose line color , style. want able visually show current selection is.

currently, know can using 2 seperate widgets, qpush button, , widget make myself draws line across using qpen.

i turn these 2 widgets single widget. want widget pushable "button" user presses , can signal out of run routine sets new qpen.

is functionality built in? or need create new widget re-implements either qpushbutton or qactionbutton? or should make widget listens mouseclick events on , create signal slot there?

you use qlabel, set style sheet, , use line on graph. use bounds of qgroupbox define x , y axis.

maybe this:

yourqlabel.setstylesheet("qwidget {background-color: rgb(255, 0, 0); color:white; border: 1px solid black;}"); // red black border 

then can set height, width , position of qlabel based on values graph. of course work if lines on graphs rectangular. if aren't, you'll have use other qlabel.

use setgeometry method of qlabel set this.

yourqlabel.setgeometry(x, y, width, height); 

as far button, can similar if want. qpushbutton has setgeometry , setstylesheet methods.

if want tell button on click, assuming have qpushbutton object called mybutton, add header file (.h):

class yourclass {     q_object     //...     private slots:         void on_mybutton_clicked(); } 

then in source file (.cpp):

void yourclass::on_mybutton_clicked() {     // stuff button on click }
