Hi,

one more question :

How can I activate the scrollbars on a panel ?

I saw that panel is derived from ContainerControl which is derived from
ScrollableControl which should be able to do this.

Dokumentation at wiki.dprogramming.com/DflDoc is a good start
but there is no explanation about the methods.

I use the Panel as Container for a picturebox.
Picturebox or Picture inside should be larger than the panel itself and
therefore scrollable.

(In a second step the picturebox shall get a zoom funktion too. I got this working with DockStyle and Size of the picturebox.)

Thank You

DFL comes with example scroller.d that shows scrolling. It involves properties hScroll, vScroll and scrollSize.

Form is also derived from ScrollableControl and is scrollable in the same way as Panel.

Hi Chris,

yes, I've seen this and I tried to do it this way first :


// Do not modify or move this block of variables.
//~Entice Designer variables begin here.
dfl.panel.Panel panel1;
dfl.picturebox.PictureBox pictureBox2;
//~Entice Designer variables end here.

private void initializeMyForm()
{
// Do not manually modify this function.
//~Entice Designer 0.8.2.1 code begins here.
//~DFL Form
text = "My Form";
clientSize = dfl.drawing.Size(292, 273);
//~DFL dfl.panel.Panel=panel1
panel1 = new dfl.panel.Panel();
panel1.name = "panel1";
panel1.bounds = dfl.base.Rect(8, 48, 272, 160);
panel1.parent = this;
//~DFL dfl.picturebox.PictureBox=pictureBox2
pictureBox2 = new dfl.picturebox.PictureBox();
pictureBox2.name = "pictureBox2";
pictureBox2.bounds = dfl.base.Rect(8, 48, 400, 200);
pictureBox2.parent = panel1;
//~Entice Designer 0.8.2.1 code ends here.

panel1.scrollSize = Size(400, 200);
panel1.vScroll = true;
panel1.hScroll = true;



But vScroll and hScroll seem to be private members of panel :


Compiling in debug mode; use -release to compile in release mode
C:\PROGRA~1\D\dmd\bin\dmd.exe myform -version=DFL_EXE -debug -IC:\PROGRA~1\D\dmd
\import -L/exet:nt/su:windows:4.0 C:\PROGRA~1\D\dmd\lib\DFL_DE~1.LIB
myform.d(47): class dfl.panel.Panel member vScroll is not accessible
myform.d(4Cool: class dfl.panel.Panel member hScroll is not accessible

Returned status code 1


I then tried :
panel1.vScroll(true);
panel1.hScroll(true);
with the same error during compile.

I am not quite sure about my OOP know-how but could it be that the reason for getting the error is that those functions are defined :
protected final void hScroll(bool byes)

So the only way is to construct a class mypanel first ?

Greetings

Peter

ps: I really like your work

For now you will have to derive from the class to change the hScroll/vScroll; however, they will be made public soon.
