fafe65a8fc Refactor to move the responsability of SetHovered() to ItemHoverable() - previously IsHovered(). Simpler and the parallel to ItemAdd is clearer with the new name. 2017-09-28 00:21:47 +02:00

2159629e9e Removed another msileading difference between the hovered functions (IsWindowContentHoverable() uses the root window already). Sorry for the commit spam! (making small commit to easily be able to Bisect those in case I make a mistake) 2017-09-28 00:05:35 +02:00

0adcddac39 IsItemHovered(), ItemAdd(): finishing cleaning up, moved the code to IsItemHovered() so ItemAdd() is more lightweight and the two IsXXXHovered functions are now very similar, making their differences less confusing. 2017-09-27 17:21:50 +02:00

omar
344d48be31 IsItemHovered(), ItemAdd(): Fixed seemingly unnecessary comparaison of root windows, makes IsItemHovered() more consistent with internal IsHovered().
Original test was added in 6e99688fa7 should not have been using RootWindow in the first place.
The difference between public-facing and internal versions would only be noticeable with overlapped child windows, which doesn't really happen anyway

c075786d8b ItemAdd(): re-ordering the tests, submission should now be faster. 2017-09-27 16:29:46 +02:00

99c7622a1b ItemAdd(), not performing computation for IsItemRectHovered() which does them itself, allowing us in the next commit to optimize ItemAdd() and make its logic more consistent with IsHovered(). 2017-09-27 16:20:53 +02:00

24f21bd4d4 Merge pull request #1113 from Urmeli0815/ImGuiSelectableFlags_MenuItem
MenuItem: only activate on Release, not on Click (nb: and not on ClickRelease to allow opening menu and selecting something with a single click. Windows seems to behave the same, allowing to click and hold to e.g. Open then move cursor, release on Save and save gets activated)

0d56140b4a BeginCombo(): rework internals a little to make it easier to provide custom combo-like elements relying in BeginCombo().

4b82759598 SetNextWindowPos: added a ImVec2 pivot parameter for positioning a given a center, bottom-right position, etc. As a generalization of SetNextWindowPosCenter() which is now obsolete. This will be useful for combo-like popups as well.
Demo: Simple-overlay window uses the SetWindowPos pivot to select a corner to position itself at.

83e8d10fab Columns: Columns set resize based on the presence of vertical scrollbar. Not 100% sure about that but it looks like we've fixed enough bugs that this may not cause troubles anymore. (#125, #913, #893, #1138) 2017-08-20 21:08:07 +08:00

7ff1c149b5 Columns: Fixed another form of shearing made visible by the PreserveWidth option. The code was initially added in c46d5634d4 to fix because we've fixed in e42aaede42eb6d8a47cf104f3afd6057b13a61ee. (#913, #125) 2017-08-20 20:58:24 +08:00

omar
9307631c90 Columns: Removed unnecessary/misleading dummy ItemSize(). Was fixed already before, and fixed again in this branch by 3bf2af23e6. (#913, #125). End() calls EndColumns() directly. 2017-08-20 19:32:50 +08:00

fd394e1e95 Scrollbar: Comments. Fixed potential div-by-zero error which I can repro now, so added an assert to notify us if it's actually ever useful or not. 2017-08-20 16:39:11 +08:00

91d841dd5f Added PushStyleColor(ImGuiCol idx, ImU32 col) overload. (Which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicily to fix.) 2017-08-20 15:28:12 +08:00
