Hi Mike,
I noticed that when using a QCheckBox with the Text property omitted, the control defaults to a block element. When in this mode, the ToolTip property is not included in the element. I don't know if this was done on purpose, but would it be possible to include it with the next release?
I have done the following to my QCheckBox.class.php:
<?php
// Code snippet from GetControlHtml()
// (line: 41)
// ... (line: 118)
$this->blnIsBlockElement = false;
$strToReturn = sprintf('<input type="checkbox" id="%s" name="%s" %s%s%s%s%s%s />',
$this->strControlId,
$this->strControlId,
$strDisabled,
$strChecked,
$strActions,
$strAccessKey,
$strTabIndex,
$strToolTip);
?>
