Hello..


My GUI components are here..

Why am i implementing GUI components and the process by wich
you organize them into a more interesting and interactive GUI applications ?

You can still use Qt GUI libraries or the like , but what
i am doing is "learning" the Delphi and FreePascal community
how to design and to implement the following GUI components
with simple primitives of Wingraph that is like the graph
unit of Turbo Pascal:

- Button
- Label
- TextBox
- MessageBox
- Memo
- Panel
- RadioButton
- CheckBox
- ProgressBar
- TreeMenu
- Calendar

You have to know that "using" GUI libraries is much easier
but to be able to understand the "inside" of how to
implement sophisticated GUI components from
simple graphical primitives is better and is good to know.

About my nextTreeMenu GUI component, i think i will also implement soon 
and easily a TreeMenu component, that is like TreeView but it is 
constituted with two of my Winmenus and with my StringTree, i think you 
will appreciate it because it will be "powerful" because it will use a 
much enhanced version of my Winmenus.

More explanation of the GUI components..

Now the following GUI components are supported:

- Button
- Label
- TextBox
- MessageBox
- CheckBox
- Winmenus


I will soon add a more powerful GUI component called TreeMenu,
it will look like the GUI of a file manager, but you will
be able to click on the callbacks and to search etc.

Also i will soon provide you with a calendar GUI component and with a 
checkbox component.

I have corrected a small bug in the event loop, now i think
all is working correctly, and i think my units are stable, here is the 
units that have included inside the zip file of my new Winmenus version 
1.22: so i have included the my Graph3D unit for 3D graphism that looks 
like the graph unit of turbo pascal, and i have included my enhanced 
Winmenus GUI component using wingraph, and i have included the GUI unit 
that contains the other GUI components, and of course i have included 
Wingraph that look like the graph unit of Turbo Pascal but it is for 
Delphi and FreePascal.

About my software project..

As you have noticed i have extended the GUI components using Wingraph, 
now i have added a checkbox GUI component, now here is the GUI 
components that are supported:

- Button
- Label
- TextBox
- MessageBox
- CheckBox
- Winmenus


But i think that the Memo GUI component can be "emulated"
with my  Winmenus GUI component, so i think that my
Winmenus GUI component is powerful and i think it is
complete now, and i will soon add a more powerful GUI component called 
TreeMenu that will look like the GUI of a file manager, but you will be 
able to click on the callbacks and to search etc.  it will be 
implemented with two of my Winmenus and with my powerful StringTree here:

https://sites.google.com/site/scalable68/stringtree


And soon i will also implement a Calendar GUI component and
a ProgressBar GUI component.

But you have to understand me , i am implementing those
GUI components so that you will be able to design and implement
more interactive GUI applications for graphical applications
with Wingraph and such.


You can download Winmenus using wingraph that contains all the units
above that i have implemented from:

https://sites.google.com/site/scalable68/winmenus-using-wingraph


I have also implemented the text mode WinMenus, here it is:


Description
 

Drop-Down Menu Widget using the Object Pascal CRT unit

Please look at the test.pas example inside the zip file Use the 'Delete' 
on the keyboard to delete the items
and use the 'Insert' on the keyboard to insert the items
and use the 'Up' and 'Down' and 'PageUp and 'PageDown' to scroll ..  and 
use the 'Tab' on the keyboard to switch between the Drop Down Menus and 
'Enter' to select an item..
and the 'Esc' on the keyboard to exit..
and the 'F1' on keyboard to delete all the items from the list
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 all 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 (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 
parameter is the callback that will be executed when the insert key is 
pressed and 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 
it is the function "updown" , the remaining callbacks that you can 
assign are the following keys: Delete and F1 to F12.

After that you can add your items and the callbacks to the Menu by 
calling the AddItem() method like this:

Menu1.AddItem(inttostr(i),test1);

the test1 is a callback that you add with AddItem() method.

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:

===
repeat

textbackground(blue);
clrscr;
menu2.execute(false);
menu1.execute(false);

case i mod 2 of

1: ret:=Menu1.Execute(true);
0: ret:=Menu2.Execute(true);
end;
if ret=ctTab then inc(i);

  until ret=ctExit;

menu1.free;
menu2.free;

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, and if the returned value is 
ctExit, that means you have pressed on the Escape key to exit.


You can download my text mode Winmenus from:

https://sites.google.com/site/scalable68/winmenus


And my units are working with Delphi and FreePascal and C++Builder.




Thank you,
