mac: QTabWidget with large icons: how?

[davecotter]

I want nice fat icons, like this:

except obviously i want the tab buttons to enlarge to contain the icons, and i want the icon text label to be underneath the icon.

I can't seem to figure out how to do that :/

it seems that they are using a QListWidget

I believe that will work! usingsetFlow(QListView::LeftToRight)!

thanks so much!

@davecotter Are you adding tabs using https://doc.qt.io/qt-5/qtabwidget.html#addTab-1 ?

[davecotter]

no i'm laying out the dialog in Qt Designer, i set the icon size there to 32 x 32, then i'm adding icons with:

tabBarP->setTabIcon();

is this just not supported in Qt ? if not, then why ENABLE the ability to set the icon size?

setting the style like this does NOT help:

tabBarP->setStyleSheet("QTabBar::tab { height: 36px; width: 36px; }");

what i wanted was something like Qt Creator's icon bar with color icons:

Lovely large icons, centered OVER the descriptive text. Just that that's vertical on the left, and i want mine horizontal across the top.

How does one accomplish this?

Hi,

You should take a look at Qt Creator's source code. IIRC, they are using a custom style.

@davecotter I haven't inspected Qt Creator code but it seems that they are using a QListWidget. With the selected item you can use a QStackedWidget as your central widget.

@davecotter
How did you do this?

[davecotter]

@Ans1 i do not know if this helps, but here's my init code:

void	QtDlgTabs::Panel_Setup()
{
	CDialog*				dlgP(GetDialog<CDialog>());
	QListWidget				*listP(dlgP->QtGetItem<QListWidget>(Dlg_Tabs_ICON_BAR));
	Rect					iconR = { 0, 0, 64, 64 };
	CPixels					pix(iconR);
	ScCGContext				context(pix);
	Qt::ItemFlags			flags(Qt::ItemIsSelectable | Qt::ItemIsEnabled);
	float					scaleF(devicePixelRatio());

	//	doesn't work
	pix.setDevicePixelRatio(scaleF);

	static	int	s_awidthI	= 61;
	static	int	s_heightI	= 50;
	int			s_widthI	= 150;

	bool		is_prefsB(dlgP->GetPanelSet() == PrefPanelSet_PREFS);

	if (is_prefsB) {
		s_widthI = 70;
	}

	int			widthI		= s_widthI;

	if (is_prefsB) {

		if (dlgP->GetAllControlsVisible()) {
			widthI = s_awidthI;
		}
	}

	listP->setGridSize(QSize(widthI, s_heightI));

	PrefPanelSet	panelSet(dlgP->GetPanelSet());
	SInt16Vec&		panelVec(GetPanelVec(panelSet));

	for (SInt16 indexS: panelVec) {
		PanelRec&			curPanel(*GetIndPanelRec(panelSet, indexS));
		QListWidgetItem		*listItemP(new QListWidgetItem());
		SuperString			nameStr(GetLocalizedPrefPaneName(panelSet, curPanel.prefPanelS));
		SDB_SourceType		iconType(static_cast<SDB_SourceType>(curPanel.sourceType));
		QFont				itemFont(listItemP->font());

		pix.clear();
		gApp->Draw_icns(&context, iconType, iconR, kTransformNone);

		itemFont.setPointSize(itemFont.pointSize() - 1);

		listItemP->setFont(itemFont);
		listItemP->setText(nameStr);
		listItemP->setIcon(pix);
		listItemP->setFlags(flags);

		listP->addItem(listItemP);
	}
}
