Hello all,

I can't seem to be able to set a negative range on the property grid slider control.

For example, if I want the slider to be from -100 to +100, how can I do that?

In the PropertyGrid sample, I've tried doing this (for the "Spin and Slider" item), of course checking that underlying slider window actually exists first:

->GetSliderCtrl()->SetRange(-100, 100);

but that doesn't work. It produces a slider that has a correct range, but when you try to slide it (or use the up/down buttons) to go below 0, it just stops (halfway in this example, so the range is actually set correctly, I presume).

Can you please advise on how to solve this?

Thanks,

Dennis

Hi,

Use SetMin method of CXTPPropertyGridInplaceSlider.

I tried SetMin() first and it doesn't work either :(

Hi,

Its because you have also Spin with wrong range:

Here modification in sample to make it work:

  pItem = pButtons->AddChildItem(new CXTPPropertyGridItemNumber(_T("Spin And Slider"), 60));
  CXTPPropertyGridInplaceSlider* pSlider = pItem->AddSliderControl();
  pSlider->SetMin(-100);
  //pItem->AddSpinButton();

Hi,

Yes, it works without a spin button, but how can I make it work with a spin button as well?

Thanks!

Obviously in that case you need set minimum range for spin too:

CXTPPropertyGridInplaceSpinButton* pSpin = pItem->AddSpinButton();
pSpin->SetMin(-100);

Yes, that's my stupidity - I had exactly the same piece of code as you have above, but I named the button *pButton, which already appeared before that (referencing a different class) and that didn't have a SetMin() method. Oh well...

Thank you for the help!
