Combobox Colors conflict

[DBenS]

Hi Denis,

Today working on an application I saw something that can be usefull to your library.

If we select the DARK THEME and using a BRIGHT COLOR (like BRIGHT YELLOW), the comboboxes show an ugly and unreadable text: white on yellow, in my specific case...

So, I did a little change into COMBOBOX.CS, trying to make it adapt itself to these situations:

protected override void OnDrawItem(DrawItemEventArgs e)
    {
          if (e.Index >= 0)
               {
                Color foreColor = MetroPaint.ForeColor.Link.Normal(Theme);
                Color backColor = BackColor;

                if (!useCustomBackColor)
                {
                    backColor = MetroPaint.BackColor.Form(Theme);
                }

                if ((e.State & DrawItemState.Selected) == DrawItemState.Selected)
                {
                    using (SolidBrush b = new SolidBrush(MetroPaint.GetStyleColor(Style)))
                    {
                        e.Graphics.FillRectangle(b, new Rectangle(e.Bounds.Left, e.Bounds.Top, e.Bounds.Width, e.Bounds.Height));
                    }

                    foreColor = MetroPaint.ForeColor.Tile.Normal(Theme);

                   // -------------------------------------------
                   Color FontForeColor = MetroPaint.GetStyleColor(Style);

                    if (FontForeColor.GetBrightness() >= 0.5)
                    {

                        if (FontForeColor == MetroColors.DarkBlue)
                        {
                            FontForeColor = Color.FromArgb(255, 215, 215, 215);

                        }
                        else
                        {
                            FontForeColor = Color.FromArgb(255, 0, 0, 0);
                        }
                    }
                    else
                    {
                        FontForeColor = Color.FromArgb(255, 255, 255, 255);
                    }

                    foreColor = FontForeColor;
                }

                   // -------------------------------------------

                else
                {
                    using (SolidBrush b = new SolidBrush(backColor))
                    {
                        e.Graphics.FillRectangle(b, new Rectangle(e.Bounds.Left, e.Bounds.Top, e.Bounds.Width, e.Bounds.Height));
                    }
                }

                if (this.DropDownStyle != ComboBoxStyle.DropDown)
                {
                    Rectangle textRect = new Rectangle(0, e.Bounds.Top, e.Bounds.Width, e.Bounds.Height);
                    TextRenderer.DrawText(e.Graphics, GetItemText(Items[e.Index]), MetroFonts.ComboBox(metroComboBoxSize, metroComboBoxWeight), textRect, foreColor, TextFormatFlags.Left | TextFormatFlags.VerticalCenter);
                }
                else
                {
                    Rectangle textRect = new Rectangle(0, e.Bounds.Top, this.textBox.Width, e.Bounds.Height);
                    TextRenderer.DrawText(e.Graphics, GetItemText(Items[e.Index]), MetroFonts.ComboBox(metroComboBoxSize, metroComboBoxWeight), textRect, foreColor, TextFormatFlags.Left | TextFormatFlags.VerticalCenter);
                }
            }
            else
            {
                base.OnDrawItem(e);
            }
        }

This way I can get the combo's self-adapting to any user color scheme. I guess it can be usefull to other.

Best regards.
