[Solved]Size of pushbuttons
-
"QPushButton":http://doc.qt.nokia.com/latest/qpushbutton.html extends "QWidget":http://doc.qt.nokia.com/latest/qwidget.html so you can use "geometry()":http://doc.qt.nokia.com/latest/qwidget.html#geometry-prop to retrieve width and height from the returned "QRect":http://doc.qt.nokia.com/latest/qrect.html.

eddy,
In the docs, I found,
@
int QSize::height () const @Returns the height.
How do i call the function height()?? using obj of QSize??
This is my code. I jus need to find the height and width of any button
@
cellBut[i][j]=new QPushButton();
connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));
@Thank you

"size()":http://doc.qt.nokia.com/latest/qwidget.html#size-prop return "QSize":http://doc.qt.nokia.com/latest/qsize.html object, where you can call "height()":http://doc.qt.nokia.com/latest/qsize.html#height

I'm sorry alfah, i can not understand your English clearlly. But, the size() function will return the widget's size(as we know QSize), as Eddy mentioned before, i think you need know some concept of geometry/bounding-rect.
[quote author="alfah" date="1311752432"]could u tell me how to go about it to find the size of any one of the pushbuttons?[/quote]
what do you mean alfah ? Can you give us a more detailed description ?

Hey everybody,
im sorry to restart this thread, but the following code gives me values 480 and 640
@
cellBut[i][j]=new QPushButton();
connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));
ht=cellBut[0][0]->size().height();
wd=cellBut[0][0]->size().width();
@by no means this is the size of the buttons, think its the screen size!!!!
I need pushbutton ht and width
Thank you
-
eddy,
Yup i did,
@
for(int i=0;i<6;i++)
{
for(int j=0;j<7;j++)
{cellBut[i][j]=new QPushButton(); connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction())); ht=cellBut[i][j]->size().height(); wd=cellBut[i][j]->size().width(); } }@
ht and wd gives me 640 and 480 respectivvely. which i think is the screen size and not individual button size.

what Chuck is saying is that you didn't use a parent or add them to a layout. That way they get a size.
have a look at this quick and dirty example:
@ int rows = 6;//this is convenient in case you want to alter the numbers
int cols = 7;
QPushButton* cellBut[rows][cols] ;for(int i=0;i<rows;i++) { for(int j=0;j<cols;j++) { cellBut[i][j]=new QPushButton(this); //remark the use of a parent here // connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(onClickAction()));//better way see below } } qDebug() << cellBut[0][0]->size().height(); qDebug() << cellBut[0][0]->size().width();@you might have a look at "QSignalMapper":http://doc.qt.nokia.com/4.7/qsignalmapper.html#details. There is a nice example of what you try to achieve.
