# EasyTab_AutoSize

int EasyTab_AutoSize (int panel, int tabControl);

## Purpose

This function automatically sizes a Tab control to accommodate its largest panels and the space required for the tabs.

This function is called implicitly the first time a Tab control draws itself. In general, it is not necessary to call this function directly.

| Note If the tab control was converted from a canvas control, it will not automatically set its size smaller that the original size of the canvas control.

## Parameters

tabControl | integer | The ID returned by the EasyTab_Create or EasyTab_ConvertFromCanvas function.

## Return Value
