When i run your code, i dont get horizontal scrollbar when the CollapsingHeader name goes beyond the child window, no matter if the ImGui::Text is there. Horizontal scrollbars are disabled by default, so I dont know how you got a scrollbar without a corresponding flag. If you need a horizontal scrollbar, just pass ImGuiWindowFlags_HorizontalScrollbar
to the window_flags of BeginChild(). Use ImGuiWindowFlags_AlwaysHorizontalScrollbar
if you need to have the scrollbar visible even when the text is fully visible.
Also, why are you passing true
as the child_flags to BeginChild()? It seems a bit weird to me.

We changed the signature of BeginChild() quite recently (Sept 2023)
// old
bool BeginChild(const char* str_id, const ImVec2& size = ImVec2(0, 0), bool border = false;
// current
bool BeginChild(const char* str_id, const ImVec2& size = ImVec2(0, 0), ImGuiChildFlags child_flags = 0, ImGuiWindowFlags window_flags = 0);
// Flags for ImGui::BeginChild()
// (Legacy: bit 0 must always correspond to ImGuiChildFlags_Border to be backward compatible with old API using 'bool border = false'.
enum ImGuiChildFlags_
{
ImGuiChildFlags_None = 0,
ImGuiChildFlags_Border = 1 << 0, // Show an outer border and enable WindowPadding. (IMPORTANT: this is always == 1 == true for legacy reason)
...
};
Which allowed a smoother transition, so old code frequently uses true
which will still work, but ideally should be changed to ImGuiChildFlags_Border
.
Oh, didn't know that.

Details:
This code draws a child window and a CollapsingHeader and when the length of the CollapsingHeader name goes beyond the child window, a horizontal scroll is drawn in the child window. Everything is working fine.
But if I remove the line ImGui::Text("Hello, world!") from CollapsingHeader, then the child window will no longer draw a horizontal scroll if the length of the CollapsingHeader name extends beyond the child window.
Is this how it should be?
