Since HMG-IDE is an Integrated Development Environment, it’s possible building an entire project from scratch under HMG-IDE.
But this doesn’t mean “without coding”.
So, we can develop all GUI necessities of our project via HMG-IDE; but what, always we will need some little coding.
Then we can begin our project by building a project file. This is the very first and the easiest step:
Simply run IDE.exe and then select “New Project”.
When IDE ask, select (or build a new) a working folder and give a name (say Viva_HMG) to the project. .hbp extension will be assigned by IDE to project file.
Whenever IDE build a new project, automatically build and open a module file with name Main.prg and a form file with name Main.fmg.
Module file open by your text editor and form file open by IDE itself.
The content of your module file will be like this :
#include <hmg.ch> Function Main Load Window Main Main.Center Main.Activate Return
Basic rules :
– Every HMG project have one ( and only one ) “MAIN” procedure / function
– For using GUI controls, every HMG project have one ( and only one ) “MAIN” form.
So, names of both module and form files are “Main“.
File names doesn’t mandatory;
– only name of first procedure / function of first module file must be “Main” and
– “Window Type” property of one form must be “MAIN“.
You can see “module” tab of Project Browser window “(Main)” sign adjacent to the Main.prg and at the bottom line of “Properties” tab of Object Inspector “Window Type” property of “Main” form already set “MAIN” by IDE.
Now, we can work on our first form.
First we can give a name to it.
But what happening?
There isn’t “Name” in the properties list of our form !
Yes, this is correct; because:
– Basic rule 3: Every HMG form has their own name. Only exception is: a form to be LOAD, has a unchangeable name: TEMPLATE.
In other hand, you give an “alias” to a loaded form. The way of this is using “AS” close in the LOAD command. FE:
Load Window Main AS frmIDEBS_01
In this case you have change “Center” and “Activate” commands too :
If you don’t use an “alias” in that way, you will use in all references of form by its file name; in this example : “Main”.
Now, its time to give a “Title” to the form.
For this, we will use “TITLE” property of form:
Double click “Title” and give a title in the open Input Box, say “It’s a Wonderful Life”
We can change easily background color of form:
Double click BackColor in the properties list.
In the Color Select Form select your favorite background color or simply enter these tree values. : 64, 220, 210
Press RUN button and look to your application in work.
