ColorDialog

Anonymous — Fri, 10 Jun 2011 06:05:23 GMT

when i use Autodesk.AutoCAD.Windows.ColorDialog from a modeless form, the colordialog doesn't get focus, so you have to click twice to pick the color (the first click only sets focus to the dialog)

when i put the same code in a command and run it from commandline, it gets focus

        Dim cd As New Autodesk.AutoCAD.Windows.ColorDialog
        If cd.ShowDialog <> Windows.Forms.DialogResult.OK Then Exit Sub

Hi, which version of AutoCAD are you using? I cannot see this behavior on 2012/Win7

Try this

myPalette.KeepFocus = False

Dim cd As New Autodesk.AutoCAD.Windows.ColorDialog

Dim dr as DialogResult = cd.ShowDialog

MyPalette.KeepFocus = True
If dr <> Windows.Forms.DialogResult.OK Then Exit Sub

Hav'nt done any palette programming lately, but last time I did, you needed to manage the focus yourself for the palette. Should be plenty of examples, just search on the 'KeepFocus'.'

to augusto: I'm using AutoCAD 2011, i will try it in 2012, but i don't have it installed here

to HomeBoy: I'm not opening the ColorDialog from palette, but from the Windows.Form

hi,

I could not repro this here...I tried with modeless form using Application.ShowModelessDialog and Form.ShowDialog, but the ColorDialog is always working fine....if you manage to have a sample uploaded, I can take a look.

HomeBoy: I believe the issue you´re talking is related to combo boxes on palettes, not the case here. Or do you have something different?

I can see it now...

Apparently there is a limitation with PictureBox: it cannot receive focus. It seems that this is causing the problem we see here, so I would suggest you use a flat button with no border, which is visually equal a picturebox, but can receive focus and work in this case.

How that sounds?

****,

That won't help me, as I have 450 picture boxes calling a color pallete.

Thanks as well any way for the help!
