Provides an application helper class (platform and drawing interface).
</short>
<descr>
<p>
<var>TWidgetSet</var> is a <var>TObject</var> descendant which implements an 
application helper class that provides access to platform-specific operating 
system and drawing interfaces. A number of methods are declared as abstract 
virtual, and must be implemented in descendent classes. Other methods are 
declared as virtual to allow them to be overridden for a specific platform.
</p>
<p>
TWidgetSet is used as the ancestor for platform-specific implementations like 
<var>TWin32WidgetSet</var>, <var>TGTKWidgetSet</var>, 
<var>TQtWidgetSet</var>, <var>TCarbonWidgetSet</var>, 
<var>TCocoaWidgetSet</var>, et. al.

<element name="TWidgetSet.BitBlt">
<short>
Copies part of a source DC into a destination DC, using the specified raster

</short>
<descr>
<p>
This routine implements the equivalent Windows GDI API of the same name in 
all platforms supported by Lazarus.
</p>
<p>
It copies a section of a Canvas to another one, without any stretching. It 
allows one to select the kind of operation which should be performed to draw 
the pixels into the destination in the parameter ROP. Allowed operations go 
from simply copying the pixels without change to inverting them and also to 
executing logical operations involving the source pixels and the previously 
existing pixels in the destination Canvas.
</p>
<p>
For normal usage one should only use SRCOPY in the ROP parameter, other 
operations may not be supported by all widgetsets.
</p>
<p>
There exist 16 raster operations, according to the possible combinations of 
two (boolean) values. Excluding the NOP case, that doesn't modify the target 
area, the possible values for ROP are:
</p>
<ul>
<li>BLACKNESS - Fills the destination rectangle with black</li>
<li>DSTINVERT - Inverts the colors of the destination area</li>
<li>MERGECOPY -</li>
<li>MERGEPAINT -</li>
<li>NOTSRCCOPY -</li>
<li>NOTSRCERASE -</li>
<li>PATCOPY -</li>
<li>PATINVERT -</li>
<li>PATPAINT -</li>
<li>SRCAND -</li>
<li>SRCCOPY -</li>
<li>SRCERASE -</li>
<li>SRCINVERT -</li>
<li>SRCPAINT - Combines the colors of the source and the destination using 
the operator OR on each pixel</li>
<li>WHITENESS - Fills the destination rectangle with white</li>
</ul>
<p>These flags can be added to above ROPs:
</p>
<dl>
<dt>CAPTUREBLT</dt>
<dd>
Includes windows which are on top of the specified Canvas. This option is not 
recommended and is very hard to implement in all supported platforms.
</dd>

Use PolyBezier to draw cubic Bézier curves.
</p>
<p>
The first curve is drawn from the first point to the fourth point with the 
second and third points being the control points.
</p>
<p>
If the <var>Continuous</var> flag is <b>True</b> then each subsequent curve 
requires three more points, using the end-point of the previous Curve as its 
starting point.
</p>
<p>
If the <var>Continuous</var> flag is set to <b>False</b>, then each 
subsequent curve requires 4 additional points, which are used exactly as in 
the first curve.
</p>
<p>
If the <var>Filled</var> flag is set to <b>True</b> then a straight line is 
drawn from the last connected point to the starting point, and the entire 
curve is filled with the current brush.
</p>
<p>
Any additional points which do not add up to a full Bezier (4 for Continuous, 
3 otherwise) are ignored. There must be at least 4 points to be connected.

<short>Draws a filled Polygon.</short>
<descr>
<p>
Use Polygon to draw a closed, many-sided shape on the canvas, outlined with 
the current Pen and filled with the current Brush.
</p>
<p>
The Points parameter is an array of the vertices of the polygon.
</p>
<p>
Winding determines how the polygon is filled. When Winding is <b>True</b>, 
Polygon fills the shape using the Winding fill algorithm. When Winding is 
<b>False</b>, Polygon uses the even-odd (alternative) fill algorithm.
</p>
<p>
The first point is always connected to the last point.
</p>
<p>
To draw an unfilled polygon use the Polyline method, specifying the first 
point a second time at the end.

Use Polyline to connect a set of points on the canvas.
</p>
<p>
The Points parameter is an array of points to be connected. If you specify 
only two points, Polyline draws a single line.
</p>
<p>
Calling the MoveTo function with the value of the first point, and then 
repeatedly calling LineTo with all subsequent points will draw the same image 
on the canvas. Unlike LineTo, Polyline does not change the value of PenPos.

<element name="TWidgetSet.PostMessage">
<short>
Sends a message to a window, without waiting for the message result.
</short>
<descr>
<remark>
This section was copied from LCLIntf, and may not apply to all platforms.
</remark>
<p>
This method is a thread-safe solution to send messages to windows. Those 
messages will be handled in the message loop of the application and therefore 
can be sent from any thread. They are not immediate, but they will awake the 
main thread if it is waiting for messages.
</p>
<p>
These messages can be handled by procedures with the keyword message in the 
class of a form for example. One would then use the handle of this form as 
the Handle parameter of this routine.
</p>
<p>
Custom messages should always have an identification number (represented by 
the parameter Msg) larger then the constant LM_USER.
</p>
<p>
The two parameters WParam and LParam will be passed along to the window 
together with the Msg identification number.
</p>
<p>
The difference between SendMessage and PostMessage is the way that they return 
control to the calling thread. With SendMessage, control is not returned until 
target window has completed processing the message. With PostMessage, control 
is returned immediately.

<element name="TWidgetSet.RedrawWindow">
<short>Redraws (part of) a window.</short>
<descr>
<p>
All invalidated parts of a window, which deserve an update, are collected in 
the update region. When this region is not empty, WM_ERASEBKGND, WM_PAINT and 
WM_NCPAINT messages are sent to the window, as soon as the application is 
(almost) idle. RedrawWindow can be used to force an immediate redraw instead.
</p>
<p>
WM_ERASEBKGND is optional, erases the background before painting. WM_NCPAINT 
paints the non-client areas (borders, caption...), without assistance by user 
code.
</p>
<p>
When neither lprcUpdate nor hrgnUpdate are specified, the whole client area 
of the window is affected. Otherwise the region takes precedence over the 
rectangle.
</p>
<p>
Flags specify how the window is invalidated or validated, and when repainting 
occurs. Flags other than RDW_ERASE may not be supported by all platforms.
</p>
<p>
To invalidate specify RDW_INVALIDATE, and optionally one of:
</p>
<dl>
<dt>RDW_ERASE</dt>
<dd>Forces a WM_ERASEBKGND message before painting.</dd>
<dt>RDW_FRAME</dt>
<dd>Also redraws the window frame, as covered by the update region.</dd>
<dt>RDW_INTERNALPAINT</dt>
<dd>Force WM_PAINT even if the update region is empty.</dd>
</dl>
<p>
Validation is not implemented for all platforms. To validate, specify 
RDW_VALIDATE and optionally one of the following:
</p>
<dl>
<dt>RDW_NOERASE</dt>
<dd>Suppress all pending WM_ERASEBKGND messages.</dd>
<dt>RDW_NOFRAME</dt>
<dd>Suppress all pending WM_NCPAINT messages.</dd>
<dt>RDW_NOINTERNALPAINT</dt>
<dd>Suppress all pending internal WM_PAINT messages.</dd>
</dl>
<p>
These flags specify <b>when</b> repainting will occur:
</p>
<dl>
<dt>RDW_ERASENOW</dt>
<dd>Send WM_ERASEBKGND messages before returning.</dd>
<dt>RDW_UPDATENOW</dt>
<dd>Send WM_PAINT messages before returning.</dd>
</dl>
<p>
The handling of child windows normally depends on the WS_CLIPCHILDREN window 
style flag. Clipped child windows are not normally affected by RedrawWindow. 
These flags override:
</p>
<dl>
<dt>RDW_ALLCHILDREN</dt>
<dd>Include all child windows.</dd>
<dt>RDW_NOCHILDREN</dt>
<dd>Exclude all child windows.</dd>

<element name="TWidgetSet.SendMessage">
<short>Sends a message to a window.</short>
<descr>
<remark>
This section was copied from LCLIntf, and may not apply to all platforms.
</remark>
<p>
This method is a thread-safe solution to send messages to windows.
</p>
<p>
The messages will be handled in the message loop of the application and 
therefore can be sent from any thread. They are not immediate, but they will 
awake the main thread if it is waiting for messages.
</p>
<p>
Custom messages should always have an ID higher than the constant LM_USER.
</p>
<p>
The two parameters WParam and LParam will be passed to the message handler, 
together with the message ID.
</p>
<p>
The difference between SendMessage and PostMessage is the way that they return 
control to the calling thread. With SendMessage, control is not returned until 
the target window has completed processing the message. With PostMessage, 
control is returned immediately.
