🦋 Detailed Description 🦋

Okay so, Arrow Button. Periodt.

It's a push button, right? But instead of just vibes and a label, it's got one or more filled triangles chillin' on its front. 👑

And the range? An Arrow button can have 1 to 3 arrows in a row, and they can point up, down, left or right. That's it, that's the whole aesthetic. No cap.

💅 Constructor & Destructor Documentation 💅

🌟 QwtArrowButton::QwtArrowButton (int num, Qt::ArrowType arrowType, QWidget *parent = NULL) [explicit] 🌟

The glow-up moment where your button is born, bestie. It's explicit, so no sneaky implicit conversions, we don't do that here. 💅

Parameters:

• num — Number of arrows
• arrowType — see Qt::ArowType in the Qt docs.
• parent — Parent widget

Not me leaving the Qt::ArowType spelling exactly as written, iykyk — that's how the page says it, so that's how it stays. 🙈

Quick lil note bestie: keyPressEvent (QKeyEvent *) is listed up there in the Protected Member Functions, but the page doesn't give it its own little section. Just so you're not out here searching for docs that aren't there. 🫶
