| I have a problem. My distributor really wants my color picking interface to have an imagebutton with the currently selected color. I don't know if this is possible with B+. I cannot use a DirectX drawing surface, because it is likely that other DX applications will be run while this program is running. Does anyone know how to modify a Blitz button so that it can display an image? |

| Use a toolbar. |
| ||
| Use a panel with SetPanelColor(). |
| ||
Well, I've got this, but we need some way to keep the panel on top of the button before it'll work...Type colorbutton Field button,panel Field red,green,blue End Type Function CreateColorButton(x,y,w,h,parent,red=255,green=255,blue=255,style=0) Repeat n=n+1 s$=s+" " Until n=w/8 button=CreateButton(s+"| v",x,y,w,h,parent) ;Note that "style" won't do anything, it's just ther because it is in most functions. SetGadgetLayout button,1,1,1,1 panel=CreatePanel(x+6,y+4,w-25,h-8,parent,1) SetGadgetLayout panel,1,1,1,1 SetPanelColor panel,red,green,blue c.colorbutton=New colorbutton c\button=button c\panel=panel c\red=red c\green=green c\blue=blue End Function Unless I have the wrong idea of what you want... but anyhow, this is the type of thing you see in places like "Display Properties". |
| ||
| Woah dude. Use a combination of createimage and a toolbar gadget. It will save you a TON of code and work. |
| ||
| Well, I MIGHT do that if it would look like the ones in the "Display Properties" window. Do you have any code for it that I could see? |
| ||
| You can use panels as buttons. You don't need to put a button underneath. Panels return events when clicked. In Fontext I used them for colorchip buttons and for imagebuttons. |

| I cannot use a DirectX drawing surface, because it is likely that other DX applications will be run while this program is running. What's this DX issue when using canvasses anyway? I use that technique for nearly 1.5 year now, never had any issues, except going to DOS and return (images are garbled :) but that can be restored by calcing/loading the gfx again).. Can you test this: http://quor-toth.balpol.tudelft.nl/~mvs/CS_TBL__newbutton_testapp.rar and tell me if there's ugly stuff happening somehow, in combination with other DX apps? Panels have the disadvantage that you need to preload them from disk, you can't animate gfx on a panel or reload new gfx to it.. |

| Panels have the disadvantage that you need to preload them from disk, you can't animate gfx on a panel or reload new gfx to it.. Yes you can, as long as you don't mind pulling them in from disk each time. You could even remove this (non) issue by MoleBoxing them |
| ||
| Loading from disk, that's crap ... can't run anything from a CD then.. Anyway: what DX issues are there then, and does my exe work with or without problems? (I use canvases all the way) |
| ||
| There shouldn't be any problems with DX as long as nothing is running fullscreen. Unless you know otherwise? |
| ||
| With fullscreen, do you mean a window gadget @ full screenres (1280x1024 in my case), or the console output @ fullscreen..? |
| ||
| Neither, I mean anything that goes into fullscreen mode (DX) using a Blitz style Graphics mode. Example: Graphics 800,600 |
| ||
| Yeah, that's what I meant with that output console.. ok, so during apps/games in a real window, there's no issue using canvases instead of panels.. btw, even if for some reason there would be a real image-button some day I still wouldn't use it. I had a bad experience with some small app I made 2 weeks ago; something related to updating a canvas after an ASyncKeyState keypress went wrong once a normal button was pressed while remaining focussed.. |
| ||
| One word... TOOLFREAKINGBAR. USE A TOOLBAR!!! |
| ||
| If you showed me some code, then MAYBE I would. But being so insistant isn't going to help you. |
| ||
| The toolbar suggestion is good, but saving a temporary image to the harddrive and reloading it every time you change the color...that's crap. |
