Hi,

I would like to change the font of an object during runtime, but MUIA_Font is only useable at object creation.
It only works if I close and reopen the window, after I set MUIA_Font to a TextFont structure returned by OpenDiskFont().

But in the MUI Prefs its possible to change the font without closing and reopen, so my question is how can I do that too?

Font size is used to calculate the (min) size of the object and therefor the window so changing it on the fly might cause layout problem.

Easy fixes:

- Use gfx.library functions in MUIM_Draw to render text

- Put the object into a group and only remove/add that object when needed (don't forget to call Init/ExitChange on the group)


Without knowing further details it is impossible wether any of the above applies.

I wanted to know how MUI Prefs does this, you can change the font there and all objects using this font will be changed immediately.

My guess s on something like my 2nd fix

I do InitChange, then I set MUIA_Font, then ExitChange.

Ok, now I do InitChange, OM_REMMEMBER my obj , set MUIA_Font, then OM_ADDMEMBER and then ExitChange.
This way it works!

As for MUI and as in the subject, is there Lamp.mcc as AmigaE module available?

I can send it to you later, I think I have it.
I have also done a new MUI module where the names are the same as in the C header and with many macros to easily create custom classes.

@r-tea: Here is an archive of my AmigaE modules for some .mccs.

Thanks a lot! Gonna make use of it soon.

Edit:
I use EC v 3.3a. It woun't read these modules.

I used ECX to compile the modules, but I included the source so you could compile with EC if necessary.
