Yes, I am using wxFormBuilder.
All I did is just created new Project:
File->New->Project...->wxWidgets project.
As Preferred GUI builder I select wxFormBuilder, Frame Based, then some other options, and as I click finish, it ask to confirm, that CodeBlocks\share\CodeBlocks\templates\wizard\wxwidgets\rc\resource.rc file will be overwritten,
then CodeBlocks\share\CodeBlocks\templates\wizard\wxwidgets\wxfb\frame\GUIFrame.cpp will be overwritten,
then CodeBlocks\share\CodeBlocks\templates\wizard\wxwidgets\wxfb\frame\GUIFrame.h will be overwritten, and
CodeBlocks\share\CodeBlocks\templates\wizard\wxwidgets\wxfb\frame\WxWizFrame.fbp will be overwritten.
Then it creates a project, where this files are also in a project tree with the whole path, where my CB is located (D:\Soft\SDKs\CB... and so on) but the project is located in D:\MyProjects\wxWidgets\ProjName dir.
