I use at my application angular directive drawing-manager (https://developers.google.com/maps/documentation/javascript/examples/drawing-tools). I would like to get all object, which I have on map, when I press a button save. It is possible? What have to I use? I need save the objects to database and than again draw to map. Or is another opportunity?
It seems there is currently no way to do this with the DrawingManager.

Someone will have to take whatever is in FreeDraw and implement into the drawing manager to keep track of the shapes drawn. Good Luck.

What approach to do intelligent drag drop like this in react? (canvas or non-canvas based approach?). That is to use React (with a library such as React DND) without using cavas, OR move to rendering/drawing this within React using HTML 5 "canvas" (with potentially a library such as "react-konva".
Requirements:
when dragging the item, the other items behind "move" to calculate
and show what the final re-arrangement will look like (if the drag is
allowable)
may be drop points for which move is not allowed so would highlight
this as well (e.g. if some other items in the timeline were "locked")
I have checked React DND, react-konva, and others. The issue they use the transform property and that prevents moving the placeholder separately from dragging the item.
So here is the custom implementation: https://codesandbox.io/s/drag-swap-qv6s0x
P.S
It is still unfinished (buggy), later I will fix and clean up the code. But for now, I would like to share it, to know is it what you wanted or if I missing something.
Have a look at this online documentation for MDBootstrap:
https://mdbootstrap.com/docs/standard/plugins/drag-and-drop/
Go to "Horizontal example" section, this might be what you are looking for.
Edit: Sadly this is a premium feature :(
Well, I'm a newbie. I'd like to write an app in WPF. The main purpouse will be in drawing predefined elements/objects. Input from user is mostly realized by text boxes - numbers. But I'd like to add some kind of user input into drawing itself too + zooming and moving. Next functionality will be in saving the draw for later loading and another editing (printing maybe, but it's far far away).
I can imagine something like this:
due to some user interaction I'd prefere to use of InkCanvas
i want to define my own elements/objects with some properties. But where it will be define? Some external file maybe?
the save file will be composed of XAML code only
I will study this more lately, but I want to know if my thoughts are in the right way.
Are these points correct, or completely bullshit? :)
Thanks, and sorry for English...
I don't know if this is exactly what are you looking for, but here a little list of advice to help you on reaching your goal:
First of all, if you are crating an application, you should see this before. It explain the Model-View-ViewModel pattern, which is essential when you are creating something on WPF. This can help you abount your 2nd point.
Regarding your save file, i don't know exactly what you have in mind, but it depends on what do you want to save exactly. If you want, InkCanvas have the option to export directly the work in a bitmap . If you need to store some setting, depending on your need you can work with Settings or Resources
InkCanvas seems the appropriate tool for your need. Of course you will have to build your app around this control
I was wondering that currently we have gtk.TextViewWidget to display the contents of widget. I was wondering is there any way to make a type of My Computer Properties dialog box where there are different panels at top and one can click on any one of them to display the contents of that property.
Can anyone give me some good advice on how to proceed making this?
Sounds like you need a GtkNotebook.
I'm not sure I understand fully what you mean, but it sounds as if you could easily just stack a GtkTreeView on top of a GtkTextView to achieve what you want. Populate the tree view with a suitable model holding the items in your computer (how to find this information is of course a separate problem), and then as a tree item is clicked, modify the text view's buffer to display the associated information.
Hi I am trying to implement a mspaint like application in wpf.I have successfully implemented most of the basic drawing functionalities by implementing a custom stroke class.Now I am trying to implement the Text inserting option from mspaint.I have tried to implement using DrawingContext.DrawText,it is working alright but when I save the strokes to an isf file and reloading the drawing,all the drawing is loaded but the text is not restored.Please help me on the same.
I'm afraid the Text is a member of the Children collection. Your StrokeCollection, which is what you're asking to do the serializing and deserializing, doesn't know anything about it. You're going to have to build serialization logic yourself, or go through a DataContractFormatter, or whatever permutation of same you prefer.
I am currently loading the default file, page.xaml, but in that page, I am loading the content from another xaml file. With each "page" change, I just load the content from a different xaml file, and on and on.
Example: this.Content = new StartPage();
I'm running into some syntax issues, however, because of the way I am changing my content, and was wondering if there is a definitive answer on how to accomplish this?
For example, when trying to capture user's keystrokes, I would normally do:
this.Keydown += new KeyEventHandler(this_KeyDown);
but that event handler doesn't even fire in my situation. So, I'm looking for a new approach to my content-switching approach before revisiting the keystroke problem.
Have you looked at using Silverlight 3. It has a new Page Navigation functionality.Silverlight 3 Navigation
As far as content switching goes, I've always done what you propose in the question. Normally I create a MainPage.xaml which has has the frame of the application (usually a Grid for me). One of the cells in the Grid is considered the content area of the app. When the user takes an action that I would consider to be navigation, I create a new instance of a Page, which for me is a file like MyUserControl.xaml, and then add it to the appropriate content cell in the Grid. MainPage stays around for the life of the application and assists with navigation.
If you want something fancier, and want to take advantage of browser based back/forward buttons, you could look into the SL3 navigation like Correl suggested.
A Big problem with what your're doing is that journalization doesnt take place automatically when you swap out framework elements by creating them and plugging them in the codebehind. This means that you lose the back and forward functionality of the browser. You can manually journalize stuff when you swap out pages, but this is simply a hack to get your navigation approach working.
Take a look at Prism at www.compositewpf.codeplex.com/, specifically the MVVM method of GUI design, it'll save you alot of time later on. And remember, you dont need to go hardcore when you look at MVVM, u could always cut out alot of "dynamic" functionality if you're a one man band
Also swap to silverlight 3 and use the navigation application. If you cant, take a look at helix 0.3, it'll provide a more asp oriented approach to navigation. the link provides a really really good starting point, its a three part article, i suggest you read all three and download the sample application and understand it.
A book could have been written on your question, this has to suffice for now.
