Qt/C++ Chaning buttons parameters in loop
-
Hello,
For example, i have few buttons.
Button1, Button2, Button3;
I want changing for example visibility or disabled options in loop.
Like in c++, when we have int array.
for(....)
{
array[i] = i *5;///for example
}In similar way,did i can creat array of button and changing paramters like visbility.
For example:
for(....)
{
button[i] = visibilty(false);?
}Now to do similary things, i make addidional bool variable, for example visibility and i set this on false.
Thats how look my code.
if (visibility == false)
{
ui->button->setVisibility(true);
visibility = true;
}Can somebody help find better way to make my code more automaticaly and simple?

How much more simple than that do you want it to be? You put (pointers to) your widgets into an array/QList/QVectorand then perform operations on them.If all the buttons are together and you want all of them to come & go, you could put them inside some widget to group them and then just set its visibility. But I don't know if that applies to your situation. There are also the
QObject::findChild...()methods which can be used to visit, say, all pushbuttons with a common ancestor, so you don't have to put them in an array, if that is what you want.Now to do similary things, i make addidional bool variable, for example visibility and i set this on false.
I don't understand what you are saying/asking here.

I create variabble bool parameter;
I set parameter as false.And if i want change visibilty of buttons during cliking, i do something like this.
if(parameter == false)
{
ui->button->setVisibility(true);
parameter = true;

That seems to change one button. Anyway I don't think there is a question here.
