If text or lines are blurry when integrating ImGui in your engine:
+
- in your Render function, try translating your projection matrix by (0.5f,0.5f) or (0.375f,0.375f)
- If you are confused about the meaning or use of ID in ImGui:
- - many widgets requires state to be carried over multiple frames (most typically ImGui often wants remember what is the "active" widget).
- to do so they need an unique ID. unique ID are typically derived from a string label, an indice or a pointer.
- when you call Button("OK") the button shows "OK" and also use "OK" as an ID.
+ A primer on the meaning and use of ID in ImGui:
+
+ - widgets require state to be carried over multiple frames (most typically ImGui often needs to remember what is the "active" widget).
+ to do so they need an unique ID. unique ID are typically derived from a string label, an integer index or a pointer.
+
+ Button("OK"); // Label = "OK", ID = hash of "OK"
+ Button("Cancel"); // Label = "Cancel", ID = hash of "Cancel"
+
- ID are uniquely scoped within Windows so no conflict can happen if you have two buttons called "OK" in two different Windows.
- within a same Window, use PushID() / PopID() to easily create scopes and avoid ID conflicts.
- so if you have a loop creating "multiple" items, you can use PushID() / PopID() with the index of each item, or their pointer, etc.
- some functions like TreeNode() implicitly creates a scope for you by calling PushID()
- - when dealing with trees, ID are important because you want to preserve the opened/closed state of tree nodes.
- depending on your use cases you may want to use strings, indices or pointers as ID. experiment and see what makes more sense!
- e.g. When displaying a single object that may change over time, using a static string as ID will preserve your node open/closed state when the targeted object change
- e.g. When displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state per object
- - when passing a label you can optionally specify extra unique ID information within the same string using "##". This helps solving the simpler collision cases.
- e.g. "Label" display "Label" and uses "Label" as ID
- e.g. "Label##Foobar" display "Label" and uses "Label##Foobar" as ID
- e.g. "##Foobar" display an empty label and uses "##Foobar" as ID
- - read articles about immediate-mode ui principles (see web links) to understand the requirement and use of ID.
+
+ - when passing a label you can optionally specify extra unique ID information within string itself. This helps solving the simpler collision cases.
+ use "##" to pass a complement to the ID that won't be visible to the end-user:
+
+ Button("Play##0"); // Label = "Play", ID = hash of "Play##0"
+ Button("Play##1"); // Label = "Play", ID = hash of "Play##1" (different from above)
+
+ use "###" to pass a label that isn't part of ID. You can use that to change labels while preserving a constant ID.
+
+ Button("Hello###ID"; // Label = "Hello", ID = hash of "ID"
+ Button("World###ID"; // Label = "World", ID = hash of "ID" (same as above)
+
+ - use PushID() / PopID() to create scopes and avoid ID conflicts within the same Window:
+
+ Button("Click"); // Label = "Click", ID = hash of "Click"
+ PushID("node");
+ Button("Click"); // Label = "Click", ID = hash of "node" and "Click"
+ for (int i = 0; i < 100; i++)
+ {
+ PushID(i);
+ Button("Click"); // Label = "Click", ID = hash of "node" and i and "label"
+ PopID();
+ }
+ PopID();
+ PushID(my_ptr);
+ Button("Click"); // Label = "Click", ID = hash of ptr and "Click"
+ PopID();
+
+ so if you have a loop creating multiple items, you can use PushID() / PopID() with the index of each item, or their pointer, etc.
+ some functions like TreeNode() implicitly creates a scope for you by calling PushID().
+
+ - when working with trees, ID are used to preserve the opened/closed state of tree nodes.
+ depending on your use cases you may want to use strings, indices or pointers as ID.
+ e.g. when displaying a single object that may change over time (1-1 relationship), using a static string as ID will preserve your node open/closed state when the targeted object change.
+ e.g. when displaying a list of objects, using indices or pointers as ID will preserve the node open/closed state differently. experiment and see what makes more sense!
