Added BETA api for Tab Bar/Tabs widgets. (#261, #351) (merged this feature from the from Docking branch so it can be used earlier as as standalone feature)
- Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API. - Added ImGuiTabBarFlags flags for BeginTabBar(). - Added ImGuiTabItemFlags flags for BeginTabItem(). - Style: Added ImGuiCol_Tab, ImGuiCol_TabHovered, ImGuiCol_TabActive, ImGuiCol_TabUnfocused, ImGuiCol_TabUnfocusedActive colors. - Demo: Added Layout->Tabs demo code. - Demo: Added "Documents" example app showcasing possible use for tabs.

The addition of new configuration options in the Docking branch is pushing for a little reorganization of those names.

Other Changes:
|
||||
- Added BETA api for Tab Bar/Tabs widgets: (#261, #351)
|
||||
- Added BeginTabBar(), EndTabBar(), BeginTabItem(), EndTabItem(), SetTabItemClosed() API.
|
||||
- Added ImGuiTabBarFlags flags for BeginTabBar().
|
||||
- Added ImGuiTabItemFlags flags for BeginTabItem().
|
||||
- Style: Added ImGuiCol_Tab, ImGuiCol_TabHovered, ImGuiCol_TabActive, ImGuiCol_TabUnfocused, ImGuiCol_TabUnfocusedActive colors.
|
||||
- Demo: Added Layout->Tabs demo code.
|
||||
- Demo: Added "Documents" example app showcasing possible use for tabs.
|
||||
This feature was merged from the Docking branch in order to allow the use of regular tabs in your code.
|
||||
(It does not provide the docking/splitting/merging of windows available in the Docking branch)
|
||||
- Added ImGuiWindowFlags_UnsavedDocument window flag to append '*' to title without altering
|
||||
the ID, as a convenience to avoid using the ### operator.
|

- Resizing windows from edge is now enabled by default (io.ConfigWindowsResizeFromEdges=true). Note that

- dock: docking extension
|

- dock: dock out from a collapsing header? would work nicely but need emitting window to keep submitting the code.
|
||||
|

- tabs: re-ordering, close buttons, context menu, persistent order (#261, #351)
|

- tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing.

- tabs: persistent order/focus in BeginTabBar() api (#261, #351)
