DirectX GUI Controls

[chronozphere]

I think you are doing it the right way. DirectX is very low-level so it doesn't contain any mouseover functions. You can retrieve the mouse-position using DirectInput but you can also use the default Delphi-Events or WINAPI functions, it doesn't matter. I use the standard delphi events to retrieve mouse coords.

So i guess your code is the way to go. If it works for you, it's OK

ok great, thanks chronozphere...

now i jus need figure out how to create a border around buttons and dialogs etc, any pointers you could give me?

also problem finding info on rendering an image to the window, ie as the background image.. thanks again, you've been very helpful

*edit* here is what i have done so far > http://www.meka-meka.com/meka/Nemesis.rar

I'm glad i can help.

A border around a button and a button image can be done by rendering textured quads. For texturing i would suggest this tutorial:

The only difference is that you need a Quad (rectangle), not a pyramid. I'm sure you can figure out the coordinates for a textured quad yourself.

This way, you can render images. You can use them as background for your window, or titlebar. You can also use them for your buttons. If you only want a border for your buttons i would suggest you use an image that is transparent in the center, and only has color at the borders.

You can get even cooler effects when you combine Diffuse colors with textures. You can give your images colors, and blend them with the background. You have to include D3DFVF_DIFFUSE and D3DFVF_TEX1 in your texture format definition. Also make sure that your renderstates and sampler-states are correct. This can be a little tricky. Check the following tut (alpha blending only):

When i get home.. i will take a look at your work so far.

hi, great thanks, only problem is that if the virtual form size is changed, it will strentch the texture and make the border bigger ? as i'd like to try make it resemble a real form... thanks again

[chronozphere]

Hmm.. that's true.

Then i would suggest you render a quad for each side of the dialog (Textured or not)

ok yes that is what i will do thanks, what do u think of my test app?

[Memphis]

hm im having few problems also with this line

[pascal]NemRes.FFont.DrawTextA(nil, 'testing', -1, @NemRes.FFontPos, DT_NOCLIP, $026AFE);[/pascal]

i have created the font object etc, nemres is a struct fontpos is a rect

as soon as i call this the app uses 100% cpu and stops rendering.

any sugestions ?

thanks in advance.

hi, ok i've been messing around i missed a char is why it didnt render the text, however, now as soon as i move the directx window, it uses 100% cpu.

*edit* nm that, i have solved the problem, thanks anyways

Yummie.. draggable windows I like that.

Your test app looks great so far. Keep it up.

hi, when my app is rendering, no matter what spec of pc, it seems to sit around 60fps, and uses 0% cpu no matter what.... but if i cover the window with another, it continues its routines but runs at 50% cpu and goes at around 2300fps.. i checked your nasha engine for reference and i see it also uses around 40-50% cpu....

so i tried running the render process on a seperate thread in a constant loop, but it stil used 0% cpu and sat at 60fps. again covering the window then moving the window out of the way, caused it to run at 2300fps for a v.short period, is there any hints or tips you could give me on this situation?

thanks in advance.
