Here is a way way to manage the Scroll Bar for the ScrollAreaGadget

With Editor Factory 1.15, In ObjectDrawing_Frame procedure, you have to add the Swap before and after \pDrawingCallback

Code: Select all

Swap \iX, iX : Swap \iY, iY
\pDrawingCallback(\iObject, iWidth, iHeight, \iCallbackData)
Swap \iX, iX : Swap \iY, iY

Code: Select all

; Example_ScrollArea_Gadget.pb

; Includes the program file
XIncludeFile "EditorFactory.pbi"

; Initializes the Module
UseModule EditorFactory

UsePNGImageDecoder()

Hello, ChrisR.

Good example, that's not bad :D

There are still some small bugs but it's not bad at all.
I encourage you to improve :)

Hello Shadow,

The Panel Gadget example looks good

For the ScrollArea, there are some display issues when resizing.
Some data is missing in the DrawingCallback procedure to reposition the scrollbars and redefine the offsets.
*Object\iX, *Object\iY is not up to date at that time and I don't get the values with GetObjectX(Object), GetObjectY(Object).

Is it possible to Add them ? something like this in the ObjectDrawing_Frame procedure:

Code: Select all

Swap \iX, iX : Swap \iY, iY
\pDrawingCallback(\iObject, iWidth, iHeight, \iCallbackData)
Swap \iX, iX : Swap \iY, iY
It's just an example of a possible ways.
I will wait for the next version and new features, EditorFactory has a big potential :D

Hi Stargate, okay, I've been thinking about additions.

It would need a command, to disable / enable, the possibility to select the object with the mouse selection.

And also commands to return if the object is selectable or not with the mouse selection square, I explain.

It is useful if you don't want an object to be selectable with mouse selection square, be careful, it has nothing to do with selection of the object itself (the object selection border).

It means that an object will be able to show or not show its selection border if the object is selected or if I click on the object, like here, no change.

But if I disable the possibility that the object is selected with the mouse selection border, then the object is not taken into account if I select it with the mouse.

So if for example I select objects and one of them is not "selectable", then this one is not taken into account in the selection, and if I move objects, those that are not selectable will not move, because they will not be "selectable" with the mouse selection box, do you understand what I mean?

For example it can be used to create scrollbars, the bars will not be "selectable" with the mouse selection box.

Imagine for example that I select objects and "scrollbars" objects with the mouse selection box, then the "scrollbars" will not be selected.

Well, I think you get the point.

Now I also need another function to change the display of the mouse selection on the objects, currently the selection overlaps the objects, I would like a function so that the selection goes below the object and not above it.

You see, it can also be used to make scroll bars, because that way the mouse selection will go under the bar and not over it!

I hope you understand what I'm saying.

@ChrisR, this is especially for you ;)

Editors Factory is only at the beginning of these possibilities, it will grow, and become a bulldozer and all broken !!!

Re: EditorFactory - Module for object management in a Canvas

Hi, I prefer the first code, I find it more realistic despite its bugs.

Yes, It is more realistic, for sure, with the "Fake" ScrollArea in background,
But with the overlay it will be difficult to remove flickering, i guess

On the 2nd example the arrow images were not well chosen.
I have updated the example with more appropriate images, it's better and only the scroll bar is missing.
Only EditorFactory features are used and it's better for drawing gadgets, attached images,... without flickering

I don't know what STARGÅTE has planned for The frame functions
It would be nice to be able to define the position (X, Y, width, Height) to manage borders and inner size
Rather than dealing with:

Code: Select all

SetObjectFrameOffset(Object, ScrollAreaBorderWidth(Gadget), ScrollAreaBorderHeight(Gadget))
SetObjectFrameClipping(Object, #True, 0, 0, ScrollAreaBarWidth(Gadget) + ScrollAreaBorderWidth(Gadget),...
SetObjectBoundaries(Object, 0, 0, GetGadgetAttribute(Parent, #PB_ScrollArea_InnerWidth)-ScrollAreaBorderWidth(Gadget),...

Stargate is a little busy, but it's there.
I also proposed some things, did you see?
I really think it can help :)

Thanks for your code, we'll do a good thing when it's time !

By adding SendMessage WM_SETREDRAW, there is no more flickering and it works well this way for the Scrollbars, now.
Not sure if my examples are appropriate in this thread, sorry for the inconvenience if it is not. As it is here, I have updated the previous example

Very good work @ChrisR.
It works well that way.

This can be further improved, when the
new functions will be there.

Dear developers, is the development of this module continues?

Yes, I'm still working on it, but during the last weeks I was too busy with other things, that there was no time for Editor Factory (this is not the only PB project I have).
I will renew the frame-system and will check out, how I can make the interactive with a panel gadget and scrollbar gadget more easy.
During this time I will go through your posts to check all feature requests.

Re: EditorFactory - Module for object management in a Canvas

Short statement from my side.

I have re-written the frame system.
Now, all objects have one "universal" frame, but also can have multiple indexed frames.
The "universal" frame can be used for normal attachments without clipping and so on.
For the indexed frames only one is shown at the same time. The indexed frames have to added to the object first, like in Pure Basic with AddGadgetItem, then other object can be added to this frame.

As I can see, you want to use the images of PB gadget as object images, but for now you have no access to interact with this images (like clicking on the scroll bar or on a panel tab). Up to now I'm not sure how I/we can handle this without program the whole gadget itself, which is not the purpose of this include.
Would it help if I include an additional callback, which is called during the event handling? In this callback you would then have access to the local mouse cursor position and mouse events to check for clicks and hovers.
But how do you know the metrics/dimensions of the scrollbar or a tab in a panel gadget?

@Amitris_de: Please check your post, because all images are invalid and I can no longer see what you wanted to show.

@ChrisR: "I don't know what STARGÅTE has planned for The frame functions

What do you mean with (X, Y, width, Height)?

@ShadowStorm: I saw your featuzre request with the disable / enable option for the selection frame. I will check it.

Thanks for the rewriting of the frame system :)
and for the possibility to have multiple indexed frames
STARGÅTE wrote:What do you mean with (X, Y, width, Height)?
It should be more explicit with an example:
The Panel childrens are written in the frame with an offset compare to GetObjectX(Y) of the object Panel :
x = 3 for the left Panel border
y = 25 for the Tab height (24) and top Panel border (1)
If the frame of an object Panel could be defined with (iObject, iFrameIndex, 3, 25, Panel_ItemWidth, Panel_ItemHeight)
It would no longer be required to define SetObjectFrameOffset(Object, LeftOffSet=3, TopOffSet=25)
And boundaries could be defined with something like SetObjectBoundaries(Object, 0, 0, #Boundary_FrameSize, #Boundary_FrameSize)

For a ScrollArea with #PB_ScrollArea_Raised (border=3px)
The frame could be defined with (iObject, iFrameIndex, 3, 3, ScrollArea_InnerWidth, ScrollArea_InnerHeight)

I hope i'm clearer
However, I don't know if it's something that can be done in your powerful module
