Any way to force a signal?

[dbrmik]

Hi

I would like to force a set signals (from combo boxes and spinboxes) to call slots in my application even though the indices have not changed. Is this possible?

Best regards

Yes. Just create your own signals and emit them whenever you want.

Can I do this with QComboBox and QSpinBox?

e.g

emit iterSpinBox->valueChanged(DEFAULT_ITERS);

gives me a compile error "is protected withinn this context"

Hi,

SLOTs are functions, so call it directly.

[JimDaniel]

Yes, just like ^NyAw^ says, a slot is just a function so you actually don't need signals. Here is an example:


int combo_index = myComboBox->currentIndex();
mySlot(combo_index);

Thanks Jim,

I thought there might be a way of setting values in my comboxboxes which would force an automatic call to my slots. This happens if the index values change from their defaults but not if they remain the same

[JimDaniel]

You ought to post your code, but as long as your connections are made before you do whatever you are doing in SetDefaults() then the signals should be properly emitted.

Thanks Jim, ^NyAw^

Yes, the connections are made before setDefaults() is called. I suppose what I was looking for is a way to propogate the settings of my spinboxes to MyClass even if their values have not changed ( I am now called the slots directly)

Thanks for your time
