TCS_GroupBox

This class manages group boxes in the
Goldenseal small business estimating software,
project management software, construction estimating software
and construction software.

It's a class for creating a group box with a caption, for basic interface use.

SUPERCLASS = CTCS_Caption

Constructor

/*********************************************************************************
constructor from stream. This justs sets our RGB to a default value
*********************************************************************************/
CTCS_GroupBox::CTCS_GroupBox(LStream *inStream)
: CTCS_Caption(inStream)
{
mEdgeColor = CTCS_RGBColor::GetGrayColor();
}

Source Code

/*********************************************************************************

DrawSelf

draw the group box

*********************************************************************************/
void CTCS_GroupBox::DrawSelf()
{
TCS_Rect frameR;
CalcLocalFrameRect(frameR);
DrawGroupBox(mText, mTextInfo, frameR, mEdgeColor);
}
/*********************************************************************************

DrawGroupBox

draw a group box. This is a separate static function because it is
used by the layout editor group box class
