SetDropDownWidth with combo label

Created a combo box with xtpComboLabel style. By default, the drop down width of combo is the width of combo + width of label which makes drop down appear below label. I htink it should be width of combo only, makes visual funny. Also, if I adjust the width of drop down to be smaller to be same as combo, the left edge of drop down is always at left which makes it not align with combo.

I think default behaviour should be drop down width is equal to width of combo only, and drop down left edge should always be align with left edge of combo.

Or is there a way to adjust this already ?

It is designed behaviour and works like in Office products.

For 9.80 we will add xtpFlagLeftPopup flag support for CXTPControlComboBox.

you can patch your sources now to allow it:

in void CXTPPopupBar::UpdateFlags()

replace

m_popupFlags = xtpPopupDown;

to

m_popupFlags |= xtpPopupDown;

because you must add xtpFlagLeftPopup  flag.

in OnCreateControl function also add

pControlCombo->SetFlags(xtpFlagLeftPopup);

Ok, now it is working.

I noticed there is a function: CXTPControlComboBox::GetLabelWidth()

Is there a way I could use this function to find the proper width of drop down to use ? I tried using it in OnCreateControl but the label width is 0 at that time.

I tried this:

case ID_COMBO_DAYS:
{
    m_pComboDays = new CXTPControlComboBox();

    if( m_pComboDays )
    {
        m_pComboDays->SetFlags(xtpFlagLeftPopup);
        lpCreateControl->pControl = m_pComboDays;
        m_pComboDays->SetStyle(xtpComboLabel);

        int nMyWidth = 70;
        m_pComboDays->SetWidth( nMyWidth );
        int nLabelWidth = m_pComboDays->GetLabelWidth();
        //Unfortunatly label width = 0
        m_pComboDays->SetDropDownWidth( nMyWidth-nLabelWidth );
    }
}
