HVGA is the default panel size. Documentation on this topic is found on sdkj_xlet_develop_panel_eR112.pdf (page 12). This document section describes the default behavior regarding display panel and DALP file correlation. The document notes the following:
“Description of display-mode element in DALP file is not required when creating an application that is compatible among models containing HVGA/WVGA/SVGA display panels.”
This implies that in order for the GUI to be compatible among all 3 display sizes, the GUI should be designed for the smaller size panel display (HVGA) as HVGA is the default panel size when display-mode is unspecified. Page 100 on sdkj_xlet_develop_xlet_eR113.pdf denotes the following:
<!ATTLIST display-mode size CDATA #IMPLIED>
If unspecified, it assumes HVGA.
IMPORTANT:
Note 1
If uWVGA or 4-line display panels are among the targeted panels, then these panels must be specified on DALP file parameters.
Note 2
Please check individual MFP features to obtain actual panel’s available size for GUI creation.
