I think so simple operation like this:
Code: Select all
oImage = QPixmap():new()
oImage:load(cValue)
Self:setPixmap(oImage)
should work. But it won't
I have no idea.
I'm not sure since I've not seen your complete code, but, consider that the harbour level object is not the same as QT object, meaning that 'self' is not the same as ::oQTObject.

Hello Roberto!
I've commited my code for IMAGE class souce\label.prg and samples\demo_1.prg
It won't work, but, maybe later, I'll find few minutes to work over it.

Hi Friends,
Here's the GRID control Create Method() code snapshot attached on this post, though unfinished but somehow I'd be able to scratch the tip of the iceberg. I prefer to used the QTableView():New() but I am also a none HBQT expert so I used QTableWidget():New(). For the time being, this will be the case and as I work along, I might change this early implementation. Code comments is included as an aid on my conceptualization rather than drawing it on the paper.
Note: QTableWidget() grid with known rows and columns, QTableView() can be implemented later with setItems to increase the row and colums, e.g. rowCount( ( alias->lastrec() ) - lesstheDeletedRecs ) so that there will be no blank rows on the grid. I think it's a long way over. LOL! Anyway I think HMG.4 would work with QTableWidget while I'm working with the extension.
I will work on the properties and some methods tomorrow night. Your comments are welcome and seems to be of vital importance...
Regards,
Danny

Hi,
I forget to mention that the grid isn't working yet. What I wanted is for our Project Director, Roberto to see if what I am heading for is the right direction. Sorry, I forget to mention on my earlier post.

Ok.
The OOP design of HMG.4 is done for simplicity.
Allowing the user to call the method new() without parameters for all classes (excepting popup that requires only one).
The create() method is called automatically at parent window activation and optionally, the user could call prior to window activation for any object, but the create method must not require parameters, simply because it picks the adequate property values previously stored in variables such as ::nRow, ::nCol, etc.
So, the support for parameters in grid's create method is out of HMG.4 design.
Regarding other possible things, this is an early version yet to get some other conclusions.

Ok.
I'll take a look at it, if I found the problem I'll post a note here.

Hi Roberto,
OK. I'll post the changes here again.

Forgot your additions to demo4.prg
It takes only two lines of code to instruct to current label class to show an image instead a text.
Go to label.prg and about line #179 add this:
Code: Select all
<...>
if ValType (::lAutoSize) != 'U' ; Self:AutoSize := ::lAutoSize ; endif
qPixmap := QPixmap():new( "save.png" ) * <- NEW CODE
::oQTObject:setPixmap( qPixmap ) <- NEW CODE
// set default label word wrapping to .T.
<...>
Of course, 'save.png' must be located at your test app folder.
You could copy the current LABEL.PRG into IMAGE.PRG and start the new image class around it. Eventually, later the image class could be optimized to inherit from label, so, saving code, but now we have more important things in mind, like make it work first
