How can I set the default window size of a plot window in linux?

[brandy125]

Is there a way to set the default window size of a plot window in linux?

[GillesDuvert]

normally, setting env. var. GDL_GR_X_WIDTH and GDL_GR_X_HEIGHT should do it.

Weird ! On my Linux laptop, GDL_GR_X_WIDTH is working fine but GDL_GR_Y_WIDTH has no effect !
(too late to explore)

[GillesDuvert]

Indeed, GDL_GR_Y_WIDTH is not tested. sorry

[alaingdl]

Bad idea to test too late ! (stupid question !)

All the useful variables are prefixed by GDL_GR_X_

Do we have to consider to check the IDL ones ? (with the same logic than IDL_PATH/GDL_PATH ?) Is it useful ? Request ?

Thanks @alaingdl and @GillesDuvert!

Tthe two variables

GDL_GR_X_WIDTH

and

GDL_GR_X_HEIGHT

did the trick for me!

[GillesDuvert]

@brandy125 thanks for the test, indeed I programmed GDL_GR_X_HEIGHT and that is what the documentation says.
@alaingdl Unfortunately, I changed the code to GDL_GR_Y_HEIGHT using the GH editor in the meantime, so will have to revert the change.
