Exontrol - Grid-Gantt Chart ActiveX, NET, WPF Control

Use the ShowToolTip method to display a custom tooltip. Use the ToolTipPopDelay property specifies the period in ms of time the ToolTip remains visible if the mouse pointer is stationary within a control. Use the ToolTipFont property to change the tooltip's font. Use the Background(exToolTipAppearance) property indicates the visual appearance of the borders of the tooltips. Use the Background(exToolTipBackColor) property indicates the tooltip's background color. Use the Background(exToolTipForeColor) property indicates the tooltip's foreground color. The ShowToolTip method has no effect if the ToolTip and Title parameters are empty. Use the CellToolTip property to specify the cell's tooltip. Use the ItemBar(,,exBarToolTip) property to specify a tooltip for a bar. Use the Link(,exLinkToolTip) property to specify the tooltip to be shown when the cursor hovers the link.

The ToolTip parameter supports the built-in HTML format like follows:

 bold bolds a part of the caption.
 underline specifies that the portion should appear as underlined.
<s> ~~strikeout~~ </s> specifies that the portion should appear as strikeout.
 italic specifies that the portion should appear as italic.
<fgcolor=FF0000> fgcolor </fgcolor> changes the foreground color for a portion.
<bgcolor=FF0000> bgcolor </bgcolor> changes the background color for a portion.
  breaks a line.
<solidline> draws a solid line. If has no effect for a single line caption.
<dotline> draws a dotted line. If has no effect for a single line caption.
<upline> draws the line to the top of the text line
<r> aligns the rest of the text line to the right side. It has no effect if the caption contains a single line.
<img>number[:width]</img> inserts an icon inside the cell's caption. The number indicates the index of the icon being inserted. Use the Images method to assign a list of icons to your chart. The last 7 bits in the high significant byte of the number expression indicates the identifier of the skin being used to paint the object. Use the Add method to add new skins to the control. If you need to remove the skin appearance from a part of the control you need to reset the last 7 bits in the high significant byte of the color being applied to the part. The width is optional and indicates the width of the icon being inserted. Using the width option you can overwrite multiple icons getting a nice effect. By default, if the width field is missing, the width is 18 pixels.
<img>key[:width]</img> inserts a custom size picture being loaded using the HTMLPicture property. The Key parameter indicates the key of the picture being displayed. The Width parameter indicates a custom size, if you require to stretch the picture, else the original size of the picture is used.
text displays portions of text with a different font and/or different size. For instance, the bit draws the bit text using the Tahoma font, on size 12 pt. If the name of the font is missing, and instead size is present, the current font is used with a different size. For instance, bit displays the bit text using the current font, but with a different size.
& glyph characters as &amp ( & ), &lt ( < ), &gt ( > ), &qout ( " ), &#number, For instance, the &#8364 displays the EUR character, in UNICODE configuration. The & ampersand is only recognized as markup when it is followed by a known letter or a # character and a digit. For instance if you want to display bold in HTML caption you can use bold

The Alignment parameter can be one of the followings:

0 - exTopLeft
1 - exTopRight
2 - exBottomLeft
3 - exBottomRight
0x10 - exCenter
0x11 - exCenterLeft
0x12 - exCenterRight
0x13 - exCenterTop
0x14 - exCenterBottom

Use numeric values as strings for X and Y parameters, to move the tooltip window relative to the position of the cursor. For instance, ShowToolTp("text",,,"11","12"), means that the tooltip window is moved 11 pixels on the X axis, and 12 pixels on the Y axis, before showing it in the default position. In this case the X and Y parameters MUST be passed as strings not as LONG values.

The following VB sample displays ( as tooltip ) the identifier of the anchor element from the cursor:

Private Sub G2antt1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
    With G2antt1
        .ShowToolTip .AnchorFromPoint(-1, -1)
    End With
End Sub

The following VB.NET sample displays ( as tooltip ) the identifier of the anchor element from the cursor:

Private Sub AxG2antt1_MouseMoveEvent(ByVal sender As System.Object, ByVal e As AxEXG2ANTTLib._IG2anttEvents_MouseMoveEvent) Handles AxG2antt1.MouseMoveEvent
    With AxG2antt1
        .ShowToolTip(.get_AnchorFromPoint(-1, -1))
    End With
End Sub

The following C# sample displays ( as tooltip ) the identifier of the anchor element from the cursor:

private void axG2antt1_MouseMoveEvent(object sender, AxEXG2ANTTLib._IG2anttEvents_MouseMoveEvent e)
{
    axG2antt1.ShowToolTip(axG2antt1.get_AnchorFromPoint(-1, -1));
}

The following C++ sample displays ( as tooltip ) the identifier of the anchor element from the cursor:

void OnMouseMoveG2antt1(short Button, short Shift, long X, long Y) 
{
	COleVariant vtEmpty; V_VT( &vtEmpty ) = VT_ERROR;
	m_g2antt.ShowToolTip( m_g2antt.GetAnchorFromPoint( -1, -1 ), vtEmpty, vtEmpty, vtEmpty );
}

The following VFP sample displays ( as tooltip ) the identifier of the anchor element from the cursor:

*** ActiveX Control Event ***
LPARAMETERS button, shift, x, y
