Defining Path

Revu

I need to update different images(stored in different path) on the same PushButton at different events.How can I do this without using pustbutton->setIcon(:/pathoftheimage/image1) for the second time as pustbutton->setIcon(:/pathoftheimage2/image2) and so on.
Please help.

Thanks,
Revu

It depens what event means to you.

You can add different pixmaps to QIcon using QIcon::addPixmap() or QIcon::addFile() for different modes (normal, disabled, active, selected) and states (on, off) which are then automatically displayed when the QPushButton enters a specific state and mode.

If an event is something specific to your application there is no way around using QPushButton::setIcon(). If you don't want to have different pathes all over you code you could for example

use a central icon pool
@
class YourClass
{
...

public:
enum Icon
{
StateAIcon,
StateBIcon
};

QIcon icon(YourClass::Icon icon)
{
    return ...;
}

...

void stateAEvent()
{
    pushButton->setIcon(icon(YourClass::StateAIcon));
}

};
@

use resource aliases
@
class YourClass
{
...

public:
void stateAEvent()
{
pushButton->setIcon(QIcon(":/icons/stateA.png"));
}
};

<RCC>
<qresource prefix="/icons">
<file alias="stateA.png">someFolder/someFile.png</file>
<file alias="stateB.png">differentFolder/subFolder/someFile.png</file>
...
</qresource>
</RCC>
