#4639 — My much enhanced Winmenus using wingraph and my Graph3D units and GUI unit are here..

Hello..


My much enhanced Winmenus using wingraph and my Graph3D units and GUI 
unit are here..

Now the following GUI components are supported:

- Winmenus
- TextBox
- Label
- MessageBox
- Button


Author: Amine Moulay Ramdane

I have implemented Winmenus using wingraph, this one is graphical, i 
have also included an Opengl demo and other demos , just execute the 
real3d1.exe executable inside the zipfile to see how it is powerful, i 
will soon enhance much more my Winmenus.

Now it is both compatible with Delphi and with FreePascal, now
it works with Delphi tokyo, but there is only one difference between 
Delphi and FreePascal, the double click with the left button of the 
mouse of freepascal is replaced in Delphi with a one click with the 
middle button of the mouse to avoid a problem.

Description:

Drop-Down Menu widget using the Wingraph unit. Please look at the 
real3d1.pas demo inside the zip file to know how to use it.

Use the 'Delete' on the keyboard to delete the items
Use the 'Insert' on the keyboard to insert the items
and use the 'Up' and 'Down' and 'PageUp and 'PageDown' on the keyboard 
to scroll ..
and use the 'Tab' on the keyboard to switch between the Drop Down Menus
and 'Enter' on the keyboard or mouse double click(for FreePascal) or 
middle mouse click(for Delphi) to select an item..
and the 'Esc' on the keyboard or right mouse click to exit..
and the 'F1' on keyboard to delete all the items from the list
and right arrow and left arrow to scroll on the left or on the right

You can search with SearchName() and NextSearch() methods and now the 
search with wildcards inside the Widget is working perfectly.

Winmenus is event driven, i have to explain it more to you to understand 
more...

At first you have to create your Widget menu by executing something like 
this:

Menu1:=TMenu.create(5,5);

This will create a Widget menu at the coordinate in characters (x,y) = (5,5)

After that you have to set your callbacks,cause my Winmenus is event 
driven, so you have to do it like this:

Menu1.SetCallbacks(insert,updown);

The SetCallbacks() method will set your callbacks,  the first callback
is the callback that will be executed when the insert key is pressed and 
here above it is the "insert()" function, and the second callback is the 
callback that will be called when the up and down keys are pressed and 
here above it is the function "updown" , the remaining callbacks that 
you can assign are the following keys: Delete and F1 to F12.

After that you have to set your callback function, cause my Winmenus is 
event driven, so you have to add an item with AddItem() and set the 
callback function at the same time, like this:

AddItem('First 3D opengl demo',test1);

test1 will be the callback function.

After that you will enter a loop like this , the template of this loop 
must look like the following, that's not difficult to understand:

Here it is:

===

while true do
   begin
   if mouse1.click
   then
   begin

   ret:=Menu.Execute(true);
   if ret=ctExit
    then
     begin
      break;
     end;
   Menu.Execute(false);
   end;
   end;


==

When you execute menu1.execute(false) with a parameter equal to false my 
Winmenus widget will draw your menu without waiting for your input and 
events, when you set the parameter of the execute() method to true it 
will wait for your input and events, if the parameter of the execute 
method is true and the returned value of the execute method is ctTab 
that means you have pressed on the Tab key.. if the returned value is 
ctExit that means you have pressed on the Escape key to exit.

I have also included my Graph3D unit for 3D graphism, and i have 
included GUI.pas unit that comes with more GUI components, please look 
at the demo.pas demo inside the zip file to know how to use my Winmenus 
unit and GUI unit to do GUI.

About the Graph3D unit: it looks like the Graph unit of turbo pascal but 
it's for 3D graphism, and to understand the variables  Rho,Theta,Phi,DE 
of the InitProj() method of Graph3D unit, please read what's below:

When you run the demo program that is called cube3d.pas ,  here is the 
keys of the keyboard that permits you to run it:

Right arrow: to increase the angle Theta(that is the variable Theta) to 
move in the  plane XY anti-clockwise.

Left arrow: to decrease the angle Theta(that is the variable Theta) to 
move in the plane XY clockwise.

Top arrow: to increase the Phi(that is variable Phi) angle to move up 
and look at the cube from above.

Bottom arrow: to decrease the Phi(that is variable Phi) angle to move 
down and look at the cube from below.

Key A: to decrease R(that is variable Rho) to get closer to the cube, we 
can even penetrate it and pass behind, in the latter case the image 
obtained will be the opposite.

Key E: to increase R(that is variable Rho) to move away from the cube.

Key +: to increase the distance D(that is variable DE) between the 
screen and the eye, this causes an enlargement of the image.

Key -: to decrease the distance D(that is variable DE) between the 
screen and the eye, this causes the image to shrink and possibly be an 
inverse magnification if D becomes negative, ie if the screen passes 
behind the observer.

Key C: to move from perspective projection to parallel projection and 
vice versa. During this toggle the parameters which were current are 
stored in auxiliary variables (RhoResp, DEResp for the perspective and 
RhoPara, DEPara for the parallel projection) in order to be able to 
return to it correctly afterwards.

Key F: To end the runnning program.

Language: FPC Pascal v2.2.0+ / Delphi 7+: http://www.freepascal.org/

Operating Systems: Windows..

And the following define configurations inside the defines.inc file:

{$DEFINE CPU32} for 32 bit systems

{$DEFINE CPU64} for 64 bit systems
