TreeView new version
|
| |
Prompted by a query from a developer, I was looking at TreeView, and I realised I hadn't uploaded the latest version to my web site. So version 0.13 is now up there. I've also uploaded a distribution packaged in the correct manner (ie inside a !Boot structure) to make it easier for end users to install the modules.... more »

Confusing toolbox behaviour
|
| |
Sorry, it's me again with another toolbox question: I have created a res file with a number of windows (auto-create and auto-show set to no). Now I have a table which contains three names of the windows in the template. And I have a loop which cycles through this table and tries to create the windows and store the object IDs.... more »

FontInstall/FontRemove
|
| |
I have started to find the use of FontInstall a little 'flaky' on my RPC RO6.10, after many months of no problems with it. It now seems to be showing symptoms which I know happen on some (but not all) Iyonix machines. I am using FontInstall once in the !Run file of an application (to install a moon phase font for !Calibre, if that matters) and the... more »

Moving the pointer in C
|
| |
Hi All, How do you move the pointer in C? I've discovered OS_Word,21 in the StringHelp (and real) PRMs but am confused about how to use it.[1] What's the difference between the "pointer" and the "mouse"? What is "LSB" and "MSB". What is the structure of the block which you're supposed to pass to the SWI?... more »

Determine string dimensions when font painted to screen
|
| |
Hi Guys, I am in need of checking the length of a string, in order to fit it onto the screen. I have no trouble painting the string to the screen. I assumed SWI scanstring or stringWidth is what I need but am unsure what needs to be done to test it? Cheers Michael

Filer like windows
|
| |
I intend to write a program that can keep a number of images and draw files in memory at the same time. The user should be able to access every file individually. What I plan to do is a window that contains every available file like in a filer window. I would also like to have the option to show large icons/small icons/full info and maybe later even a... more »

Elucidation Needed
|
| |
Hi All, I've been battling with a bug in WinEd for some time and seem to have developed a solution, but I'm concerned that I might not have got to the bottom of the problem as I don't understand why my solution should make any difference.... So I thought I'd post here in case anyone can spot what I've missed or... more »

Has anyone got IyonixMesa to work on the FX5200 card?
|
| |
Hi. The subject line pretty much says it all I'd like to be able to use the graphics accelerator in the Iyonix, and OpenGL seems to be a good way for that. I've come across the IyonixMesa site ([link] however, I haven't got any of the prebuilt example programs to run on my Iyonix (which has the... more »
