Other changes:

|

- IO: Added GetPlatformIO() and ImGuiPlatformIO, pulled from 'docking' branch, which
|
||||
is a centralized spot to connect os/platform/renderer related functions.
|
||||
Clipboard, IME and OpenInShell hooks are moved here. (#7660)
|

- IO, InputText: fixed an issue where typing text in a InputText() would defer character
|
||||
- IO, InputText: fixed an issue where typing text in an InputText() would defer character
|
||||
processing by one frame, because of the trickling input queue. Reworked interleaved
|
||||
keys<>char trickling to take account for keys known to input characters. (#7889, #4921, #4858)
|
||||
- Windows: adjust default ClipRect to better match rendering of thick borders (which are in
|
||||
theory not supported). Compensate for the fact that borders are centered around the windows
|
||||
edge rather than inner. (#7887, #7888 + #3312, #7540, #3756, #6170, #6365)
|
||||
- MultiSelect+TreeNode+Drag and Drop: fixed an issue where carrying a drag and drop
|
||||
payload over an already open tree node would incorrectly select it. (#7850)
|
||||
- MultiSelect+TreeNode: default open behavior is OpenOnDoubleClick + OpenOnArrow
|
||||
when used in a multi-select context without any OpenOnXXX flags set. (#7850)
|
||||
- Made BeginItemTooltip() and IsItemHovered() with delay flag infer an implicit ID (for
|
||||
ID-less items such as Text element) in a way that works when item resizes. (#7945, #1485)
|
||||
- MultiSelect+TreeNode+Drag and Drop: fixed an issue where carrying a drag and drop payload
|
||||
over an already open tree node using multi-select would incorrectly select it. (#7850)
|

- MultiSelect+TreeNode: default open behavior is _OpenOnDoubleClick + _OpenOnArrow when
|

used in a multi-select context without any ImGuiTreeNode_OpenOnXXX flags set. (#7850)
|
||||
- Tables: fixes/revert a 1.90 change were outer border would be moved bottom and right
|
||||
by an extra pixel + rework the change so that contents doesn't overlap the bottom and
|
||||
right border in a scrolling table. (#6765, #3752, #7428)
|
||||
- Tables: fixed an issue resizing columns or querying hovered column/row when using multiple
|
||||
synched instances that are layed out at different X positions. (#7933)
|
||||
- Tabs: avoid queuing a refocus when tab is already focused, which would have the
|
||||
side-effect of e.g. closing popup on a mouse release. (#7914)
|
||||
- InputText: allow callback to update buffer while in read-only mode. (imgui_club/#46)
|
||||
- InputText: fixed an issue programmatically refocusing a multi-line input which was just active. (#4761, #7870)
|
||||
- TextLink(), TextLinkOpenURL(): change mouse cursor to Hand shape when hovered. (#7885, #7660)
|
||||
- Tooltips, Drag and Drop: made it possible to override BeginTooltip() position while inside
|
||||
a drag and drop source or target: a SetNextWindowPos() call won't be overriden. (#6973)
|
||||
- Style: added PushStyleVarX(), PushStyleVarY() helpers to modify only one component of a ImVec2 var.
|
||||
- Fonts: made it possible to use PushFont()/PopFont() calls accross Begin() calls. (#3224, #3875, #6398, #7903)

a drag and drop source or target: a SetNextWindowPos() call won't be overridden. (#6973)
|

- PlotHistogram, PlotLines: register item ID and use button behavior in a more idiomatic manner,
|
||||
fixes preventing e.g. GetItemID() and other ID-based helper to work. (#7935, #3072)
