Custom controls

[gbernaldo82]

Hi, good morning!

I'm new in the discussion sections, so, please, bear with me if the questions has been asked before. I trieed to look for sth similar but I didn't find anything. So, my question is if there is any possibility to create custom controls and if so, how can I do it? Is there any section in the documentation (or maybe some example) about how to do it?

By custom controls I mean controls with custom behaviour (for example, a button which expands a panel when is pressed over it) instead of custom look and feel.

Thank you so much in advance!

I've been testing the SDK and I think is vereything I need in my life :D

Hi @gbernaldo82! Thank you for use NAppGUI-SDK.

For create custom controls you have to use View component, that allows you to draw anything and get the mouse/keyboard events. You have several examples:

https://nappgui.com/en/demo/die.html
https://nappgui.com/en/demo/bode.html

You can also use the undocumented API drawctrl.h that allows you draw some items with the native look. e.g Headers and Checkboxes. Take a look to ListBox and TableView. In NAppGUI these components are "custom controls" instead a wrapper over native components.

On the other hand, if what you are looking for are controls that change the morphology of the interface, take a look at these demos.

If this doesn't solve your problem, open an issue indicating what exactly you need to see the best way to implement it.
