                Hi,</div>
        <div>
                &nbsp;</div>
        <div>
                According to the documentation that seems to be the solution, but:</div>
        <div>
                &nbsp;</div>
        <div>
                (require (lib &quot;class.ss&quot;) (lib &quot;mred.ss&quot; &quot;mred&quot;) )</div>
        <div>
                (define config (new gl-config%))</div>
        <div>
                (define bitmap (make-gl-bitmap 100 100 config))</div>
        <div>
                (define dc (new bitmap-dc% (bitmap bitmap)))</div>
        <div>
                (send dc get-gl-context)</div>
        <div>
                &nbsp;</div>
        <div>
                still returns #f.</div>
        <div>
                Maybe there is something here which I do not understand.</div>
        <div>
                &nbsp;</div>
        <div>
                Thanks for any help.</div>

                Hi&nbsp;Peter,<br />
                <br />
                You&nbsp;are&nbsp;supposed&nbsp;to&nbsp;use&nbsp;make-gl-bitmap&nbsp;to&nbsp;get<br />
                a&nbsp;bitmap&nbsp;for&nbsp;which&nbsp;a&nbsp;gl&nbsp;context&nbsp;can&nbsp;be&nbsp;created.<br />
                <br />
                Otherwise&nbsp;you&nbsp;may&nbsp;or&nbsp;may&nbsp;not&nbsp;get&nbsp;GL&nbsp;ability&nbsp;in&nbsp;your&nbsp;bitmap.</blockquote>
