Purchase QCAD professional source code

[徐亦珂辰]

Hello QCAD developers：
After purchasing QCAD professional edition, can you get QCAD source code? Get professional source code how to build applications through QT? Or, how to buy QCAD source code. Because I need to use the SDK to call some functions of QCAD to write my own program.
How much does it cost to buy the source code?

No, the source code of QCAD Professional cannot be purchased.

The recommended way to extend and modify QCAD Professional is through its ECMAScript interface:

https://www.qcad.org/en/tutorial-script-programming

C++ plugins are also possible.

If you can elaborate on you plans or let us know what part of the API you need, we can help more efficiently.

Please do not post the same question to multiple forum topics, thanks.

I need to use QCAD to view the function of importing images and drawing graphics.Can you tell me which QCAD interfaces I can call?How is the fee charged？

I need to use QCAD to view the function of importing images and drawing graphics.

Inserting an image on a drawing is an open source QCAD tool:
https://github.com/qcad/qcad/blob/maste ... e/Image.js

This creates a new drawing entity: https://qcad.org/doc/qcad/3.0/developer ... ntity.html
With the related data object: https://qcad.org/doc/qcad/3.0/developer ... _data.html

How is the fee charged？

importing images

Importing and inserting images (bitmaps) is part of the open source QCAD base:
https://github.com/qcad/qcad/tree/maste ... Draw/Image

drawing graphics

This is too generic for me to comment on. Maybe you can elaborate on this.

Import image：Using the Load DWG and PDF Format Functionality in QCAD
Draw a graph：Draw the required graphics using lines, arcs, and other functions in QCAD.Simply put, it is how I use SDK to call the interface of QCAD's functions such as drawing lines, arcs, and arcs

To open a file in the GUI is also an open source tool: https://github.com/qcad/qcad/tree/maste ... e/OpenFile
What file types and file versions that supports depends on QCAD CE, Pro or QCAD/CAM.
Apart from the fact that the QCAD GUI is not required, see tutorial link provided by Andrew.
More on the scripting interface: https://www.qcad.org/en/qcad-scripting

You will find all open source tools arranged under 'scripts': https://github.com/qcad/qcad/tree/master/scripts
The drawing tools are located under 'script/Draw': https://github.com/qcad/qcad/tree/master/scripts/Draw
