Menu Arvore

Colegas,

tenho este form no qual tem o menu arvore, e um jdesktopPane:

<div class="lightbox-wrapper"><a class="lightbox" href="/uploads/3X/c/7/c74e8050372654bcf691e282f1476bb437942dd9.png.webp" data-download-href="/uploads/default/c74e8050372654bcf691e282f1476bb437942dd9" title="image.png"><img src="/uploads/3X/c/7/c74e8050372654bcf691e282f1476bb437942dd9.png.webp" width="690" height="297" srcset="/uploads/3X/c/7/c74e8050372654bcf691e282f1476bb437942dd9.png.webp, /uploads/3X/c/7/c74e8050372654bcf691e282f1476bb437942dd9.png.webp 1.5x, /uploads/3X/c/7/c74e8050372654bcf691e282f1476bb437942dd9.png.webp 2x" data-small-upload="/uploads/3X/c/7/c74e8050372654bcf691e282f1476bb437942dd9.png.webp"><div class="meta">
<svg class="fa d-icon d-icon-far-image svg-icon" aria-hidden="true"><use xlink:href="#far-image"></use></svg>image.png1050×453 23.8 KB<svg class="fa d-icon d-icon-discourse-expand svg-icon" aria-hidden="true"><use xlink:href="#discourse-expand"></use></svg>
</div></a></div>

Gostaria de clicar sobre o menu Familiar, e o form abrir sobre o jdesktopPane, para que não tenha que ficar abrindo vários forms.

Esto usando esta codificação:

private void jTree1MouseClicked(java.awt.event.MouseEvent evt) {

String menu = jTree1.getLastSelectedPathComponent().toString();

if(menu.equals("Familiar"))
{
    if(familiar == false)
    {
        FormCadFamiliar obj = new FormCadFamiliar();
        jDesktopPane.add(obj);
        obj.setVisible(true);
    }
}
