[Chameleon] scalebar widget/ print friendly page/session

[Brent Lund]

Jacob, 

 

As a follow up.   

 

Using the code below, my print preview generates a session map file
which indeed shows the scale bar label to be white.   However the next
time I zoom (change extent, map layers) on the original page the
scalebar label is Black.   So there must be another place in the session
variables where the scale label color is set.

I'm evidently missing something in reverting.   After I call CWCExecute
to generate the page, I reset the scalebar label to white, but the
initial page is not seeing this.  (It's still using the label color
kicked out by the print friendly page)

 

...

  $oApp->CWCExecute();

session_start();

$oApp->moMapSession->oMap->scalebar->label->color->setRGB(255,255,255);

$_SESSION['gszCurrentState'] = $oApp->moMapSession->saveState();

session_write_close();

...

Hi Brent,

 

Whatever you do after your widget changes the style of the scalebar gets
applied to your session in general once you use this command:

 

$_SESSION['gszCurrentState'] = $oMapSession->saveState();

 

So either avoid having to save the changes to your session, or revert
whatever it is you did as soon as your image has been produced, and then
save it again.

 

regards,

 

Jacob

	I have a page where the scalebar background is non-white and the
scalebar text is white.   The user has the option to view a "Print
Friendly" page where the scalebar has black text.   The problem is after
viewing the "PF" page, the scalebar on the original page takes on the
properties of the "PF" page.   I know the session variables are being
changed - is there a way to either prevent or undo the changes?

	 

	Thanks,

	 

	Brent Lund
