HOWTO - hide/show a toolbar button

For buttons that exist on the toolbar you can use this function.

function toggleButton(editorInstance, itemName)
{
toolbarButton = editorInstance.EditorWindow.parent.FCKToolbarItems.LoadedItems[itemName]._UIButton.MainElement;
if (toolbarButton.style.display == 'none')
{
toolbarButton.style.display = 'block';
}
else
{
toolbarButton.style.display = 'none';
}
}


E.g. to hide the FitWindow button onload of the editor:

function FCKeditor_OnComplete(editorInstance)
{

toggleButton(editorInstance, 'FitWindow');
}


Or to toggle it onclick of an HTML element:
<span onclick="toggleButton(FCKeditorAPI.GetInstance('FCKeditor1'), 'FitWindow');">click here<span>

With of course the string in GetInstance to be your FCKeditor instance name
