[Qgis-user] Custom preset format page for print layouts

[Thomas Gratier]

Hi,

Hope the following will be more understandable from a non-coder

# Below tell you how many entries (QgsPageSize) are already present (A4,
A3, ...) before
print(len(pageSizeRegistry.entries()))
# To inspect content of first entry (was useful to understand was is
present in each QgsPageSize)
print(pageSizeRegistry.entries()[0].size)
print(pageSizeRegistry.entries()[0].displayName)
print(pageSizeRegistry.entries()[0].name)

You could run also run the following to see all infos for all preset formats

for entry in pageSizeRegistry.entries():
    print("Size: ", entry.size)
    print(f"EncodedSize: {entry.size.encodeSize()}")
    print(f"DisplayName: {entry.displayName}")
    print(f"Name: {entry.name}")

Testing after adding the part `pageSizeRegistry.add(...` show you have now
one more entry compare to before
print(len(pageSizeRegistry.entries()))

Regards

Thomas
