Implementation Details

Stores information about the SGWTextInput.

SGWTextInput(SGWWidget* parent, const SGXString& placeholder, void (*validationFunction)(), float x1, float x0, float y1, float y0, float w1, float w0, float h1, float h0);

Creates a SGWTextInput with parent SGWidget ⁽㈳㈴㈳㈮㈱㈨㈠㈫ ㈧㈤㈱㈤⁾ parent, w-distance ⁽㈳㈴㈳㈮㈱㈨㈠㈫ ㈧㈤㈱㈤⁾ coordinates (x1, x0, y1, y0, w1, w0, h1, h0), placeholder text placeholder, and callback function ⁽㈳㈴㈳㈮㈱㈨㈠㈫ ㈧㈤㈱㈤⁾ when unfocused as validationFunction.

parent being nullptr is undefined behaviour.

To avoid use after free bugs, deleting a SGWWidget directly will cause a crash. Use SGWWidget::deleteWidget to delete it safely.
