[Solved]Size of pushbuttons
-
did you use an iteration like :
@for(i = 0, i < max , ++i){
for(j=0, j<max, ++j){
//do your stuff
}
}@ -
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.
:( -
I think the problem is, you didn't set the pushbutton's size implicit. And you didn't use any layout management. So the value is not you want.
-
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.

chuck,
Yea, I have not set size of the pushbutton, But since it has been created, why doesn it give me the current size of the button. That it should do right?
:( Is it necessary to specify the size of the button while creating them?
Thank you

in case you missed my topic :
have a look at my example. also the QSignalMapper link. -
:) Thanks Eddy,
Got tht one, size now is 100 and 30 which is kinda resonable :)

You're welcome. I'm glad you made it.
And did you have a look at the QSignalMapper example?
This will make your signal slots handling much easier. -
:)
I checked that, :) its a lot more easier.
Thank you :) :)

Anyway, Enjoy Qt alfah :D

chuck,
:) well, im a beginner in Qt, so far it hasn been an enjoyment :),
gradually i hope i will love bugs:D:)
