Using a modal .NET dialog to display AutoCAD object properties| Main|

Applying a gradient fill to an AutoCAD hatch using .NET

June 29, 2007

Using a modeless .NET dialog to display AutoCAD objectproperties

In this previous postwe looked at creating a simple modal dialog and using it to

display object properties. This post looks at the structural changes you need to

make to your application for the same dialog to be used modelessly. In a later

post we'll look at the benefits you get from leveraging the Palette system formodeless interaction inside AutoCAD.

Firstly, let's think about the interaction paradigm needed by a modeless dialog. A

few things come to mind:

There is no longer a need to hide and show the dialog around selection

Rather than asking the user to select an entity, it's neater to respond to

standard selection events

We no longer need a "browse" button

We now need to be more careful about document access

Our command automatically locked the document (and had

sole access) in the modal example

We should now lock it "manually" when we access it

So we can already simplify our dialog class - here's some modified C# code, with

the browse button removed and document-locking in place:

So which event should we respond to, to find out when objects are selected? In

this case I chose a PointMonitor - this class tells you a lot of really useful

information about the current selection process. It also has the advantage of

picking up the act of hovering over objects - no need for selection to actually

happen. One other fun option would have been to use a Database event

(ObjectAppended) to display information about objects as they are added to the

drawing.

A few other comments about the code:

Predictably enough we now use ShowModelessDialog rather than

ShowModalDialog()

We have our form as a member variable of the class, as its lifespangoes beyond the command we use to show it

I've also removed the selection code; we're no longer asking for objects

to be selected

And here's the source projectfor this version of the application. When you run the

application you may experience issues with the dialog getting/retaining focus - this

is generally a problem with modeless dialogs that has been addressed

automatically by the Palette class, something we'll take a look at in a future post.

Thank you for the code sample, and I have a question?

If you have for example, a polyline in the for of a slot

when two of the sides have an arc, and you have other

polylines that meet those sides and all around that slot

to leave it as an island.

Pointmonitor do not work and I have seen other cases

where fail to select.

Is there something we can do?

I have tried to use this class before in one of my

commands to select closed areas but not always was

giving me the right one.

Then, I end up making a selection of the closed

polylines on the screen and using a function to select

the polyline by defining an internal point, instead.

Thanks!

Luis.

I have been using PointMonitor to display information

about the entity via AppendToolTipText. It works great

except for one thing: My drawing is mostly solids and if I

hover over a solid so that it is highlighted, it will actually

display the information of the solid that is behind the

object that I'm trying to get the information for.

How can I assure that I get the information for the

object that is being highlighted?

Luis -

I'm afraid your description of the geometry isn't clear to

me. Are you trying to detect when the cursor is hovering

within a particular object? Unfortunately "pick in space"

is not enabled when hovering over objects - the

PointMonitor doesn't pick them up. Unless I've

misunderstood...

Tom -

I'm not sure why this is happening. One thought is to

make sure you're not picking the wrong item from the

list (assuming there are more than one entity returned

by the PointMonitor). I tried to reproduce the problem in

my own code, but it seemed to work OK - a lot may

depend on which visual style you're working with, etc.

Kean

Kean;

Excuse my bad explanation :(

Let see if I can explain better this time, by providing a

short sample that can give you an idea:

Draw an ellipse (with pellipse=1), then draw a rectangle

to enclosure that ellipse in the center.

Then, draw a line that divides the rectangle, can be

drawn vertical or horizontal. Then use the commandbpoly and generate two new closed polylines in the

areas between the rectangle and the ellipse on the

center.

Erase, the original rectangle, and the line, and now call

or use the pointmonitor, it won't select the ellipse, I

know it can be brought up with draworder and later use

the pointmonitor.

The sample I provided it is very simple, but in the case I

was thinking of using it it gets more complex, and the

idea is have an easy selection, that's why I end up

using a point inside the areas.

Hope, you are not sleep when reading this last line.

Thanks!


Luis,

I think the PointMonitor is working OK... check out the

latest post in this seriesto see if the code in there

helps.

Hi Kean,is it possible to have some examples of dockable

modelss dialogs using .Net? (no palettes)

thanks a lot in advance

David

David said...


Hi David,

The parent of CAdUiPaletteSet (the internal

MFC/ObjectARX class the PaletteSet wraps) isCAdUiDockControlBar, which is not exposed through

the .NET API.

So PaletteSet is currently the way to go for

implementing a dockable modeless UI inside AutoCAD

using .NET.

Is there a particular reason you'd prefer not to use it?

Regards,

Kean

Hi,

1)loading

2)calling "VT"

3)terminating the dialogbox

4)recalling "VT" --> Throws an Exception! (Can't access

the object, Objectname: TypeViewerForm)

Regards,

David

Hi David,

It seems the form is betting disposed, and we then want

to bring it up again. One option is to call this.Hide() in

the closebutton handler, but we'd then have to set the

dialog not to show the "X" button.

The better option is probably to check for the availability

of the form inside the VT command implementation,

creating it again, as necessary:

[CommandMethod("vt",CommandFlags.UsePickSet)]

public void ViewType()

{

if (tvf == null || tvf.IsDisposed)

tvf = new TypeViewerForm();

Application.ShowModelessDialog(null, tvf, false);

}

Cheers,

Kean

Hi Kean, sorry if this is not relevant, but I would like to

draw the AutoCAD objects like lines and circles on the

dialog itself (or part of the dialog, a dialog item). Is this

possible?

Your help is greatly appreciated.

Cheers, Nabil.

Hi Nabil,

If you need to display entities from a drawing or even

temporary entities you add on the fly, you should look at

the BlockView sample.

Kean

".. you may experience issues with the dialog

getting/retaining focus - this is generally a problem with

modeless dialogs.."

Hi Kean,

Would you please help me in finding a way to get/retain

focus in a modeless form?

Many Thanks,

Hi ali,

I can't, right now. You might try posting to the

AutoCAD .NET discussion group, to see if

someone there can help.
